Why are so many racist and sexist words allowed?

Spell the n word with an A when you call someone it, no problem. I see it all the time. Call people homophobic slurs repeatedly? No issue. No bans, see and hear the same people doing it often. Tell people you want to suck them off or for them to suck you off, no issue. Repeatedly call people names like troll because you pick something they dont approve of as a character or spell, call people trash, terrible, and every other word? See these people all the time doing it without issue.

I see these people over and over and see it directed toward everyone in the room by them. They get reported. Nothing seems to happen.
