No, no, no. "People weren't complaining when the Rebels took over" is not ever mentioned in the films.
Again, look directly at the films, nothing else.
And the Rebel Alliance wasn't a political party. It was a terrorist cell.

Looking at the films and nothing else, I think both Death Stars were built by military personnel, evidenced by that scene in which one Lieutenant (whose name I can't even pretend to remember) complains to Vader that he needs more men if he is to complete the Death Star on time. Considering how the only "men" we ever
see (based on the movies alone) on the Death Star are military personnel, it follows that the men he asks for, the men constructing the Death Star, are military personnel as well. I mean, he could be talking about outside labor, but there's never any mention of it.
I also don't think people buy stock in a planet-destroying weapon. Just not sure if anyone would pick up on that investment.
If your point is that "Freedom Fighters" equal "Terrorists," well, I actually might be inclined to agree with you in a lot of cases. But in those cases "terrorists" aren't always working for "evil." One could argue that the American Revolution was made up of terrorists.
Oh, and the Rebellion wasn't a political party, but in an Empire, I don't think political parties exist or are even allowed.
Sure, the Alliance did kill millions of people, but the majority of those were military. Alderaan was not a military target. The Death Star was. The Empire was using Alderaan as blackmail against Leia.
It's true we don't see the oppression of the Empire in the films, but it was considered to be a given. The audience was expected to know that the Empire was oppressive. The movie wasn't meant to deal with the question of whether or not "Rebels" are always the good guys, therefore the movie didn't address it.
The books and other films are canon because Lucas said they were. Tolkien never said card games or other things were canon and therefore LotR doesn't apply to this logic.
Another oppressive feat we
do see in the films is the murder of Luke's Aunt and Uncle, again hardly military or rebellious. True, they were probably withholding information from the Empire, but that hardly warrants -death-.
