There’s a subset that are a little too fascinated with the image of the Empire. Same with the Zeon fans.
To be fair zeon is arguably just as evil as the earth federation so it’s either be a fan of the boys in derpy guntanks or of the men in zakus
Well, in the original trilogy they really didn’t outright do anything we can clearly point to as wrong (except for blowing up a planet). We get very little information on either the rebellion or the empire except they’re the good guys or bad guys.
Star Wars in general has this problem where the good guys are squeaky clean and the bad guys are comic book villains without any background. That’s why Andor is the best thing to happen to Star Wars at least since Disney purchased them, if not ever. It actually fills out why the rebellion exists and what they have to do to survive. They aren’t these perfect good guys anymore and we get to see how boring the evil of the empire actually is, and how willing so many people are to follow along as long as it benefits them.
