Here’s Lemmy.world explaining why. Essentially, for having stances common to communists (opposing western hegemony is a big one they took issue with). Lemmy.world is run by your standard DNC-style liberals, they generally oppose Marxism and communism, and uphold the DNC as good. Some are also zionists.

Now, that’s my perspective as a communist. I’m a Marxist-Leninist, my perspective is as someone who reads theory, does light org work, etc. I’m not a fan of the DNC, I support socialist states, etc. Others may give a different perspective, but it’s also worth noting that there are entire drama communities dedicated to taking comments out of context, witch-hunting communists, etc and this is made even worse by defederation because it creates this “boogeyman” that .world can’t actually see.

Hope that helps, honestly you can just scroll grad and hexbear yourself for a bit without making an account to see what’s up.

From what I’ve seen, it appears a very vocal minority of .world users cannot tolerate any criticism or viewpoints opposing capitalism/liberialism or NATO.
