Regarding your last point: With the various engagement-increasing algorithms driving what information you actually see, it can be a challenge to see outside your own bubble. It takes active effort to not just see your own perspective reflected back at you and that’s by design.

A lot of people won’t engage with content they disagree with and engagement drives ad revenue so it behooves companies that only care about revenue to not challenge a user’s beliefs unless it’s something extreme enough for the user to engage out of rage and disgust (which is how chuds like Andrew Tate get promoted). It’s hard to see the otherside’s genuine viewpoint when it’s constantly filtered through the lens of your own side (or what the algorithm thinks your side is).
