The administration of that site is as context-illiterate as most of the userbase. They don’t get that an expression like “ignorant slut” changes meaning depending on context, and that in your case you were drawing a reference to pop culture.

That can be used both ways, by the way. When I still had Reddit accounts, you have no idea on how much I capitalised on that context illiteracy to insult other users. Things like:

• “An actual human being, unlike you, would quickly understand this.”
• “I understand that the concept of intellectual honesty might be a bit too complex for something like you to grasp, but you can always try it.”
• “Contrariwise to what you thought through your whole life, thinking doesn’t hurt.”
• Heavily implying that the user is a pig or barn animal.
• Heavy usage of “it” towards users behaving in a specially irrational (obtuse, assumptive, wishful thinking) way.

Can you guess how many bans I got out of that? Zero. The only time that I got a site-wide ban was for telling a Nazi something like “if you like your daddy Hitler so much then shoot yourself like it did”.
