That’s fair! Marxists are most commonly found on Lemmy.ml, Lemmygrad.ml, and Hexbear.net. Lemmy.world skews very liberal and is defederated from the latter 2, so as a consequence asking on Lemmy.world gets a very oversimplified view of Marxism.

If you want to learn about Marxism, you can check my reading list linked in my top level comment or on my profile.
