I'm not saying there aren't other valid uses, just that racism is pretty much guaranteed on a no-censorship site. It _should_ be something that we can all agree on as being "bad", even when dressed in its Sunday best from the likes of Jordan Peterson.
We can agree on it being bad, but that doesn't necessarily mean that we have to censor it, and especially so when such censorship has an already-demonstrated tendency to quickly expand in scope.
