A lot of them aren't actually communists, that's a facade. I have no problem with most communists, it's a wonderful theory and I get along much better with them than actual capitalists. In fact, I suspect a lot of them aren't even people, they're LLMs.

Lemmy.ml is a mouthpiece for the CCP. They aggressively spread CCP talking points. I abandoned an old account because they followed me around and downvoted everything I posted. This was right after the reddit exodus so I was posting positive, funny memes to help Lemmy grow. They're very quick to delete and ban people who disrupt their echo chamber, and in my experience they almost never argue in good faith. A lot of them seem like bots, if you talk to them you'll get weird, non sequitur responses.

Lemmy is a easy target for propaganda, there's very little oversight.
