HOT TAKE: If Wolfenstein weren't about Nazis, some people would root for the villains.
It's natural for people to root for the villains sometimes. People love the Enclave from Fallout, despite them just being nuclear Nazis, people excuse it as being fictional and that "they're not like Nazis entirely!"
So that's why I think that if Wolfenstein weren't about Nazis, a percentage of the players would be sympathisers for them. Let's use the Wolven League or Regime as an example. In the German versions, they did everything to turn the Nazis into a generic regime. Replacing Hitler with Hailer, turning "Sieg Heil" into "Viktoria," redoing the Swastika or Reichsadler into whatever they've got. They're just a dictatorship, not THE dictatorship. So I feel like that if Wolfenstein was about freedom fighting against "The Regime," or the "Wolven League," there would be people on both sides of the spectrum.
