I don't like those, but at least you can avoid those. It's pretty fine-grained. /r/twoxchromosomes became a default sub -- which I think was not a great idea -- at some point, which I think was probably an error, since even if some people like it, a lot of people deeply dislike it.
But if you're doing censorship at the instance level, or willing-to-interact-with-other-instance level, things are less fine-grained. And in lemmy's case, there's a built-in slur filter, and I saw someone link to a comment by a lemmy dev saying that they didn't want to make it easy for right-wingers to use lemmy. I'm not really keen on going into a platform that takes the idea that censorship should happen at a platform level.
