I'm not sure how wanting historical accuracy is pro-nazi.

Does a WWII war movie that accurately portrays the actions of Nazis feel pro-Nazi to you?

Imagine instead they used some other stand-in for what Nazis really looked like. 100 years later, people will watch the movie and not make the connection between the people in the movie and the Nazis because the symbols aren't the same.

Not a good outcome.

This attitude that "we shouldn't accurately portray history because it's icky" is ... bad.
