Ironically I think “extreme racism” is fine for people to post, while “ordinary bigotry/extremism” aren’t necessarily so. Often times, the super racist stuff isn’t actually being hostile or antagonistic, they’re just stating some super fucked up views (often in a polite way). Whereas run of the mill bigotry is often super heated, hateful, directed at someone, etc.

Conspiracy theories should always be allowed unless you’re afraid of actual discussion and truth lol. like what you got to hide? conspiracy theorists just have some wacky beliefs, what’s the problem?
