Captain America is a hero that stands for too many conservative western values, which is not to be tolerated in the forsaken landscape of current Marvel comics. So they had to tinker with the character motivations of the hero and the villain. Since all they have in their arsenal is everyone I don’t like is Hitler they had their Hitler character just start saying things their political opponents would say. Try to confuse and muddle the ideological playing field by claiming the hero and the villain want the same thing. Make even mild patriotism synonymous with third reich authoritarian nationalism. Saying hey let’s have borders and waging war on the world to extend your borders are the same thing right? When your opposition has completely reasonable arguments…just put them in the mouth of an insane dictator right… let’s make them sound ridiculous. Problem is not everyone is that stupid. When you call even minimal defense of American (western) values nazism (hydra) to anyone with half a brain this doesn’t discredit the values Captain America stood for it simply discredits the villain status of your villains. They tried to make Cap the bad guy but instead made Red Skull a good guy. If you make hydra synonymous with conservative/libertarian values you just made hydra a good thing and to anyone whose beliefs are based in ideas and not just labels they would have no problem making it the new label/symbol for those beliefs.
Of course none of this made for a good story, none of it was believable. It was a failed ideological assassination attempt of a fictional character. I was never a big Captain America fan I don’t care about the comics too much, it just blows my mind how petty and transparent that whole thing was. It annoys me how entertainment value was tossed out the window and pushing a political agenda took the steering wheel. And I absolutely love that the response was complete rejection and the resounding response of “hail hydra.”
