Exactly. If I were to armchair psychoanalyze them, I'd say they're probably the same sorts of people who become alt-right, except on the left. Blatant black-and-white thinking. Treating absolutely everything as a team sport. Eschewing all nuance. Having a weird sense of nationalism for dictatorships that commit genocides and human rights abuses. Obsession with some grand "conspiracy" involving "elites" holding society back from prosperity. Blaming LGBT and other perceived "degenerates" for being privileged elites also holding society back from prosperity somehow. Tendency to simp for strong-men and dictators.

They fit a lot of Umberto Eco's 14 signs of fascism.
