Yes, people who unironically support Leninism, Stalinism and Maoism are supporters of autocratic, and in many cases tyrannical politics. These are first principles for the vast majority of people who study politics, all over the world. It only feels strange because places like hexbear and lemmygrad have this extremely weird liturgy, where vaguely expressing any form of the idea that some forms of autocracy can be more evil than some forms of capitalism is the worst sin.
Really, the only thing which is confusing to me is why anyone who espouses egalitarian and queer friendly principles would associate with people who actively promote a global alliance of countries who would exterminate them. I don't condone association with campists for the same reason I don't condone association with Republicans.
