They get to feel superior to vast swaths of the population without doing anything.

Emotions are stronger then intellect, much stronger. And most of these people suffered in bad childhoods and were drilled or neglected into disempathy. (That’s not the necessary reaction to such childhoods but it’s a common reaction.)

I was raised in a left-leaning, progressive, atheist, LGBTQ+/minority-accepting household, but one surrounded by a white, largely conservative exurban community. I was raised to be inclusive of others, to be thoughtful, to be curious, to be polite and empathetic. I had good* parents who supported me, and taught me to treat others well.

In the middle of fifth grade, I transferred to a magnet program focusing on STEM concepts. It took me from a school that was almost entirely white, to a school which was very much multi-racial. I was really small for my age, nerdy, and the new kid. I’d always been bullied at school, but after the transfer it got a lot worse, and got pretty severely physical. A lot of the people who harassed me the worst were black. I honestly never understood the social circles enough to know what their deal was, and it certainly wasn’t only a race thing, but the fact that many of my tormentors were black wasn’t lost on me, to be sure.

When I was 11 or so, I used all the savings from a lifetime of cumulative birthdays, Christmas gifts, etc. to buy a laptop to play games on. Pretty quickly, gaming became all I did. It was an escape, and I enjoyed it. I played whatever F2P games I could. Diablo clones, random MMOs, shitty pay-to-win FPS games, whatever. My parents didn’t supervise my activities very closely, and to be blunt, I quickly became way more savvy than them about subverting any surveillance they tried to put in place anyways.

Eventually I started looking into hacks for games. I found a really large forum (think 25k members) for sharing game hacks, and joined up. By the time I was maybe 13-14 or so, I was one of the highest-ranking moderators on the forum. I hung out in their IRC server (which definitely isn’t the internet chat-rooms you’re supposed to be careful about, those are different) all day, dabbled in making my own (occasionally illicit) software and hacks, and was firmly in the community. These weren’t good people, but I didn’t know that. When I got home from school and got online, they asked me how my day was. They cared about me, they played games with me, they were my friends. I remember I was gone for like 2 weeks when I was seriously ill, and one of them tracked me down and called my house to check in on me. I didn’t think anything of it, because of course they could do that. I’d been in a Skype call with one of them who was screen sharing the array of webcams they had access to through their botnet. I didn’t realize at the time that they were probably blackmailing people, or holding their data ransom. We just hacked in video games, none of that actually serious stuff. The malware I was toying with was just because I was interested in it, and of course, my friends must have been too, right? Just a learning exercise. I figured I might try to go into cybersecurity when I started high school and could actually start taking courses in computer topics. Programming was SO fucking interesting!

My parents didn’t know what was going on. They should have. I was barely a teenager, I can’t possibly have been hiding my tracks all that well. But then, their marriage had started to fall apart, and things were bad a home. I didn’t know anything about that then, I was in my room gaming and running communities for terrible people. The headset kept their fighting far away from me. My parents didn’t know who I was hanging out with. They had raised me well, but now they weren’t doing what they should have been. So when my friends shared hateful content with me, “interesting” videos they’d found about how terrible women were, how violent minorities were, who was I to question it? They were speaking as those with knowledge. They taught me stuff, they knew better than me. And besides, I’d been physically harassed by black people before. I’d seen it for myself, right? My U.S. history teacher was REALLY smart, and she told us (in a MN classroom) that the civil war wasn’t actually about slavery either! That was super interesting to learn! And the women they complained about weren’t me. Just because a lot of the guys I hung out with had removed for girlfriends didn’t mean they hated women, it was just bad luck with shitty women. Right?

I was a good person. I mean, I was a weird socially outcast nerd, but I wasn’t a bad person. My family was still caring. Still accepting. My Mom’s apartment was always a refuge for any of our friends, even (and especially) the queer ones who had been kicked out by their own terrible parents. They had a place to come and be safe and be themselves with us. So I was a good person too, right? Good people, smart people, they keep their online lives separate from their personal lives. They don’t talk about their online activities with others, and they don’t talk about their personal information with internet strangers in chatrooms. The only people I talked with were my FRIENDS. I ran their Minecraft servers. I discussed the Jordan Peterson videos they shared. He sounds so fucking smart after all. I hardly understand what he’s talking about, but I’m sure one day I will. And the parts I don’t understand, other people can explain to me. I laughed at their racist memes. After all, it’s just a joke. And of course, overt bigotry got stomped on. I was in charge, and I was a good person. I wouldn’t tolerate that sort of thing. But a dog-whistle is just a tool for training a pet, and we’d only ever kept cats.

I eventually joined a different gaming group on the side. We played Jailbreak in CS:S. I got really good at it. Really into it. And I stopped hanging out as much with my older friends. I still kept in touch, but I’d found a new hobby. These people weren’t good people either, but I mean, the fact that they liked my voice on mic wasn’t that they were creeping on a 15 year old who they wanted to fuck, it was because I had gotten a new microphone a few weeks ago and must have sounded good on it. I had gotten lucky though. These people weren’t great people, but they weren’t nearly as bad. They weren’t literally cybercriminals, just asshole kids on the internet. So when I became a moderator in THAT community and started running things, the community actually improved. But eventually that community collapsed, and I moved on again. And again. And again. I ended up with some Brits for a while, and “mate” settled itself into my vocabulary in a deeply unwelcome way.

I’ve been incredibly lucky. I’m 28 now. The last 14 years of my life, I’ve slowly climbed from one community to another, and mostly through random luck each of those have been better than the one I was leaving. I am surrounded now by some of my favorite people. They are TRULY good people. They care about others, and stand up for good causes. Some days, I even think maybe I might be a good person too. I wasn’t a good person. I fell WAY down the alt-right rabbit hole. I’m sure that I’ve hurt people, and I’ve made countless decisions that sicken me now. But I’ve been incredibly lucky. If I hadn’t been, I have no idea where I’d be now. Or what nonsense I’d still be believing, because everything around me told me it was normal.

When you hollow out the middle class (in the US sense of the term), people go looking for a narrative to explain it, to give them a reason they don’t get (or can’t give their children) the lifestyle they were promised in the media.

One narrative that fits is corporate greed, late-stage capitalism, enshittification and staggering corruption.

Another narrative, however, is all this rampant social change going on, people changing the demographics, changing the rules, changing definitions, changing the comfortable rules of thumb they were used to - and now everything’s shit, the two must be connected, we need to slam the brakes and catch our breath, perhaps even go backwards, and maybe conditions will follow suit. Even if they don’t, change is a loss of control, and that’s scary. We need to pull our heads in, hunker down and take back what’s rightfully ours from those we’ve been forced to share it with.

Once people start looking through that lens, everything starts self-selecting to fit - and they start thinking yeah, maybe those guys had a point.

Yes, there’s horrible shitty filter bubbles on social media and 4chan and everything else, but this stuff doesn’t take root without the underlying socioeconomic issues driving it.

As for incels - I don’t think people realise just how much social privilege is involved in having a peer group during childhood and adolescence to develop the give and take of social skills necessary for actually courting a partner. Consider the weird kids, the fat kids, the (disproportionally) poor kids, the ones with a fucked up home life, who didn’t get to form stable relationships, who didn’t get the practice at human-wrangling, who maybe ended up in a socially-isolating job, who had no ‘third place’ to hang out with people, to socialise and to meet people they might be interested in.

And once people start out without social skills, it can be really hard to pick them up; the embarrassment and exclusion that can follow small fuckups get exponentially worse as time goes on. And you don’t have to be painfully awkward, you just have to… not have game. Just enough to kick you to the bottom of the rankings, so failure (or the likelihood thereof) stacks up and becomes progressively discouraging, so you don’t try and don’t get practice.

And then it’s the same situation: the world doesn’t work for them the way they were told it would; they do all the things that they’ve heard were supposed to work (but without any of the nuance needed to do it successfully), and it just doesn’t.

For some of them, they feel like they’re getting singled out to get ripped off, or that the whole damn system is rigged; it’s a big club and they aren’t in it, as it were. So they look for a narrative, they look for someone to blame, they look for the bad guy, they look for a coherent explanation of why they’re the victim here. And of course that spirals out of control and ends up in a very bad place.

For the nazis, a big problem is the alt-right pipeline that plagues sites like Youtube, along with an unstable political climate, which generally causes radicalization (Weimer Germany is also a very good example of this phemona)

As for incels, a big problem is admittably a mental health crisis plauging many men, generally causing them to become resentful of women out of loneliness.

TLDR: Poor mental health and instability

Ok, so this is my time to admit my very shameful past. I used to be racist, homophobic, and sexist(known as the big 3). I used my religion as an excuse for the sexism and homophobia and my father(my mom isnt racist and they are divorced) and dam near everyone on his side of the family is racist so I just grew up in that culture. Once I stopped talking to him and met a lot of people from other races, i learned we are all the same. Then I stated reading the Bible, and once I did that, I obviously couldn’t continue believing in it. now I am an atheist and I don’t rely on a very very old book to come to my moral conclusions.

So basically, it’s willful ignorance, and it is always easier to blame others for your own downfalls, and it makes you feel better about your own shitty life if you can hate on someone else.

Edited for clarification.

Additionally to what has already been mentioned: People are susceptible to politics that confirm their prejudices. Right-wing political thought is largely based on confirming that whatever prejudices people hold, they are morally good and justified. Thus elevating an in-group above out-groups. That is a powerful lure.

Consider this question: how is it that anyone under the age of 40 today has ever smoked?

By the time they were born, the bad effects of smoking were well understood. By the time they were teenagers, not smoking should have been as obvious as not jumping in front of a train. People already addicted find it difficult to quit, but it in no way explains anyone starting.

The question is different and yet very similar, because the things you mention wind up in a similar way. Somehow people start in that route even though it should be obvious not to. And these things you mention are much easier to fall into than smoking because parents, family, etc are all pushing it on people. Smokers generally aren’t pushing their kids, nieces and nephews, grandchildren, etc to smoke, and somehow smoking still proliferates to some degree, just consider how much more difficult to avoid it is for those whose families are actively encouraging them to fall into these methods of belief and hate.

Fascists provide easy (but often fake) answers to hard problems. Loneliness, the fear of replacement, that kind of thing.

There’s a lot of information, there’s also a lot of misinformation. Many people don’t trust authorities, sometimes for understandable reasons, so they end up in the fringes.

Also, the Nazis, and even the Confederates, weren’t all that long ago in the grand scheme. A couple generations. Many people learn these tendencies from their family.

Also incels are somewhat different from Nazis/fascists. There’s obviously a lot of overlap. There’s always been men who had trouble with women, but I think being a male virgin after a certain age is enormously more vilified these days than it was in, for instance, the 50s, even among more progressive, left leaning groups. Admittedly, that’s anecdotal so I could be wrong.

The core of the issue is the “Just World Fallacy” sometimes also called the “Prosperity Doctrine” and a few other things. It boils down to one core idea “Good things happen to good people, and bad things happen to bad people.” Basically, everyone tends to think of themselves as, more-or-less, good people. So when bad things happen, as they inevitably do, these people start going “Huh, more bad stuff is happening to me than I’ve done bad things. WTF?” So, they come to a reasonable if flawed conclusion that “someone ELSE is doing bad things, and I’m collateral damage.” This isn’t entirely wrong, although sometimes bad things do just happen. However, since at least as far back as the Civil War (and probably since time immemorial), the people whose fault it REALLY is (i.e., the people with power and privelege) have pointed at outgroups, commonly immigrants but also slaves or Catholics or trans people, and said “THOSE people are being bad. THOSE people are why you are suffering. Give me more power and I’ll get rid of THOSE people.”

External locus of control.

Bad things in someone’s life is not their fault, but the fault of whatever scapegoat.

Can’t get a girlfriend? It’s women’s fault.

Can’t get a job? It’s illegal immigrants.

Can’t afford to do the things you like? It’s the government taking too many taxes.

Whatever problem someone has, they are looking to blame someone rather than make any changes in their own life.

Social media algorithms present different things to different people. So if you fall for a grift, the algorithm will just show you things that support the grift and never show anything that debunks it.

Someone going down a weird rabbit hole will stay on that for a long time, watching many ads along the way. Someone that starts to think “hey maybe there’s something to this thing” then immediately sees something debunking it may conclude “well that last video was a waste of time” and may decide to go do something else that’s a more worthwhile use of their time. End result, they watch fewer ads. Less revenue for the social media companies.

Weird internet rabbit holes are more profitable than seeing contradicting opinions. So the algorithms are tuned to send people down rabbit holes and not offer information contradicting them.

In case it wasn’t a typo, and just to help OP for the future…

It’s “this day and age,” not “this day in age.”

I know I’ll probably get downvoted for the pedantry here especially since everyone understands what was meant, but hopefully OP will appreciate the information about the common phrase.

Also to answer the OP’s question: inferiority complex. It runs rampant in society, especially among men.
