This was the top post when I checked Lemmy this morning.. Mod commented to mark the post NSFW, even though it wasn't NSFW as far as I could tell. Post was locked and had a ton of deleted comments.
And the places that claim to be anti-slur are actually only against some of them. I have yet to see ban "hick" or "hillbilly" or "nazi" or "pagan". The metaphor filled english language is filled with slurs.
