Why would someone who finds the whole concept of Nazi Germany so abhorrent, terrifying and pregnant with malice be playing a WW2 grand strategy game in the first place?
Assuming you do not intend to say that Nazi Germany was a nice place to be, although it sounds like it: Because it is a game about warfare in WW2, not Nazi Germany. And while the latter had a major part in the former, there is a huge difference.
If WW2 was just about the war and not the other things that are not to be dicussed here, neither the symbols nor faces would be censored. To give an example: WW1 content is not banned, I can run around with a Kaiserreich-flag all day if I want.
