Star Wars is a modern mythology. (Much ironically as Lucas intended). It provides a moral and imaginative vocabulary for a lot of people.
Andor in particular is basically a show about left wing revolution in tandem with liberal reformist/entryism against fascists that are treated as ruthless but also pathetic minions of the machine.
It’s not surprising that it fits in their world view.
You may laugh and say Redditor or “read a history book”-but in a way this is very normal. Most people don’t base their politics on some deep informed study of historical exigencies and minutia-they get it from myths, from morality plays, from narratives. Humans are narrative and meaning seeking creatures. Rational debate over dates and historiography is alienating and frustrating to most people.
But fiction provides a symbolic format in which ideas and moral lessons may be encoded or absorbed. That speaks to people at a primal level far more effectively than a history lecture.
