You’re arguing against the most prolific tankie superposters on Lemmy. He’s one of the main voices of lemmygrad and that server and hexbears are virulent -what they call Marxist leninists- which is actually more akin to stalinist thought.
They support even modern day Russia, because it’s not really about communism, but about destroying western hegemony. And they are very fond of autocratic leadership and will defend to a point of sounding silly the benefits of communist autocracies (while often living in western democratic countries).
They are quite open about being overt propagandists and regurgitate arguments from red sails, so they have a wall of links and arguments to make it seem like they have a point. It’s very obnoxious to discuss with them as they are completely inflexible on their ideology.
