Aside from the insanity of glorifying a literal traitor who orchestrated the death of thousands of US Citizens (and that is a massive underestimate of Lee's impact) and it being a lightning rod for bgotry: Why the hell would people celebrate a loser? Like, not just in terms of having supported bigotry and hate but more as someone who got his ass beat.
And holy crap are people gonna be angry at the inclusive art.
There was this kid in my 4th grade class obsessed with Hitler and Nazis apparently because he thought they were like James Bond villains or Darth Vader.
In the defense of Lucas, Vader was the hero of a tragedy meanwhile Palpatine is basically an amalgamation of three different politicians and if lucas was being completely honest Palpatine would be named Richard W. Hitler.
It's more then just Star Wars. Hollywood seems to think that cold professionals are the only way to depict nazis and nazi allegories. I wish there were more depictions closer to "are we the baddies" where they hugely miscalculated something because if their arrogance. But it's harder to write a hero character when the villain trips over themself.
Not only that, but Robert E Lee himself thought that there shouldn't be any statues to the Confederacy. After it failed, he was of the opinion that the country should move on - not glorify that time.
So not only were they building statues to a losing traitor, but they weren't even following that losing traitor's wishes on the one thing he was right about!
