DC: Universes where our heroes are portrayed Nazis are presented as the literal worst case scenarios, and stories that feature those universes always have the Nazi heroes realize they’re actually on the wrong side.
Marvel: Universes where our heroes are Nazis are the main continuity now and if you don’t absolutely love it, you’re stifling the artists’ creativity!!!!
*cough* Batman. Superman. and actually, even the Justice League have been portrayed in Nazi variants… *cough*
Hell DC even has a character that is called “Captain Nazi”.
And I know the League has been portrayed as Nazis. Get some fucking reading comprehension, bud.
