Lemmygrad and hexbear are extremist, primarily Marxist-Leninist communities which take a very narrow view of socialist philosophy and insist that this view represents the one true socialism, rejecting or even mocking basically all contemporary socialist thought which falls outside their bubble. Their knowledge of the topic actually ends up being pretty shallow, and they frequently cite philosophers who actually reject their autocratic preferences.
Basically they are “socialists” who have completely lost (or in many cases, never followed) the plot, and have reverted to a core philosophy of reactionary anti-west contrarianism. The term within the socialist community for this is “campist” but these people actually take that to an entirely different level of indecipherable discourse.
