The physical idealization of hero in art is at least as old as Classical Greece. The Greek too white for you? Turn to any pee o'sea culture you fancy (except Islam) and you'll find physical idealization of heroes in art.
He doesn't know what "deconstruction" means (although to be fair, neither does anybody).
The Third Reich is against what they called entartete kunst for a variety of reasons. The strongest was that they believe art is inherently a form of propaganda (everything is political, anyone?) and should be subjected to state scrutiny. They targeted abstract and surreal art, not because these "deconstructed" anything, but because they feared that the very ambiguity of the abstract style may allow unsavory political content to slip through censorship.
(Fun Fact: the Entartete Kunst exhibition was the most-attended travelling exhibition of modern art ever. Unwittingly, the Nazis had exposed more people to modern art than MoMA and Tate put together).
There is no parallel between Nazis and the supposed consumer revolt of comic book fans. The Nazis feared covert messages embedded in arts; comic book fans hate the extremely in-your-face, hit-you-with-a-two-ton-hammer, SJW pandering by the likes of Marvel. Although I'm not sure why should there be a "ComicGate" at this moment now that Marvel has at least publicly acknowledged the lesson (whether they'll learn is another matter).
