I'm not going to argue that there isn't a split in how women and men are portrayed in comics. That pretty much speaks for itself. My devil's advocate question is simply, "Why should they not pander to the fantasies of their primary audience?" It's good business, no matter how uncomfortable it makes you. No matter how unbalanced its portrayal of women and men.
You know what I would also find interesting? A survey of male comic readers who grew up with these books. Let's find out how many of them associated any of these characters with real humans. I know I didn't. This was a comic book drawing. I'm pretty sure even as a child I never expected women (or men) to look or act like that, any more than I expected to actually win the Dark Lord's ring from a fish-eating degraded hobbit by asking it a question that wasn't technically a riddle. Never saw either in real life, and knew the difference. I bring this up not to defend the lack of strong female physical portrayals in the comics, but to argue against the use of the word "misogyny". That's a very strong word, on a whole different level. It implies hatred. I don't think there's some hidden hatred here--just comic writers and artists who think of themselves as the primary consumers, and also like big boobs.
