I will absolutely buy all of this. I used to be interested in taking Superhero Comic fans out with outright ridicule, but I never had any standing for it. It did become more of a curiosity about how one might describe the internal consistency that leads to the kind of Science Fiction statements like @Arkandel made, how someone would have known by now. I mean, he's right, but things like that are accepted in other situations. Therefore, there is an implied logic going on where some actions are hand waved and some are reviled.
If that logic is "because it makes a good story", I'd be happy with that. Captain America going against his very reason of being is not good story. It may be forgiven as the story is revealed, it may just be bad story out of the full context, but that's the kind of thing that interests me about Superhero Comics. Not the characters, but the story.
