Saw isn’t a leftist. He’s an anarchist.

Even before the partisans, when we see him in TCW… he’s fighting to restore a monarchy and to oust the Seps. By the time we see him in Andor, he’s letting his hate and sense of betrayal carry him from standing for anything to standing against the empire. Aside from espousing authoritarian tactics, we know almost nothing about his actual politics and by the time we see him in rogue one; he’s the insurgent militia equivalent of a boomer shouting at clouds.
