High taxes, trade rescritions, no personal rights and freedoms, are what Darth Vader/Anakin Skywalker's epic and dramatic redemption is about???? No!!!!!!!

No. I didn't say that. Its just a thread of the story, it provides motive for the actions of the rebellion.

So, millions of people with families that they loved and cared about and who grieved for their losses were horribly burned to death in two fiery explosions

Just so people could have lower taxes????? What the????????

Yes. I did say that. Although to put it in such simple terms without thinking of the other reasons that justify those deaths, like the higher number of casualties at the hands of the Empire, is rather short-sighted. Alderaan didn't need to be destroyed but it was. The Empire is not shown to have empathy, but it is shown to exterminate an entire planet (with likely billions of innocents) without remorse. It all adds up to one unhappy galactic populace who want to be free. That is quite a big part of the story in OT, and is also present in the PT. Its not the main arc, but its certainly up there.
