there is little comparison to the Nazis. keeping in mind it's a medieval fantasy game, you should also keep in mind most medieval societies were racist and persecuted/killed people who didn't believe in their religion.
mainly, when you consider both cons of each faction, the stormcloaks engage in fantastic racism towards every other race in tamriel. once again, this would be common behavior in medieval society.
the empire on the other hand, is openly allied with the thalmor who are dicks and kill people on the spot who are admitted talos-worshippers.
Since the lore around Talos is really shifty, and one of the only books on the subject is basically Thalmor propaganda (The Talos Mistake), if you don't choose to trust that, then it's really your choice on whether to back the racists or the religious persecutors. I personally would rather choose the Empire because at least they attack people's belief and not their race.
