I've been around the internet a long time, and even back then when throwing slurs at each other and "making fun" of marginalized groups was, if not accepted, at least tolerated because it was considered some poor attempt at humor, I don't remember ever seeing a rule or passage in any netiquette stating it that explicitly.
It was always "we don't censor speech but don't be an asshole" with a giant asterisk about what both censoring and being an asshole meant, but I don't think I've ever seen even the worst places say, "we explicitly allow hate speech, go ahead".
Holy fucking shitballs.
That reads like some bullshit you'd find on r/iamverysmart on Reddit.
Maybe side effects of all the substances he uses to become the Übermensch.
