Most of the big-name communities on lemmy.world are political in some way, and they all have pretty severe varieties of moderation fuckery. Mods will make safe spaces for troll users posting streams of propaganda, make rules against calling out the propaganda, do totally bizarre things (MBFC bot) which they then blame on the admins saying that the admins are forcing them to do it, and then the admins will say that's not true and how could they ever get that impression. It's just a weird, noisy, and dishonest place.

And, also, because it's the biggest instance it has the biggest population of aggressively clueless or offensive users. The mods seem pretty overwhelmed being able to deal with it all. I'm not sure you can really blame that on the instance itself, since it's just what happens on a big instance, but in my opinion the low quality of the conversation might be related to the fact that the mods are apparently spending a lot of their finite amount of time apparently actively trying to make things worse.

It happens sometimes that I'll click on a post, look at the comments and get this "WTF, is it St. Patrick's Day and everyone's angry and drunk and no one told me, what is this" reaction and then notice that I somehow stumbled into a big lemmy.world political community, and so the quality of the conversation is immediately going to have a negative 200 percent penalty.

Don't go there. It is a bad place. The PugJesus historical art communities are nice though.
