This is a parody of this image: [link]
Before anything else, let me explain that I had less effort than you imagine doing this image, it's all done in one layer, for instance. I'm not trying to compete or imitate the original artist's style, this is merely illustrative. I don't care about some anatomy issues of this image, or the -many- lightsource issues in this (although the original image already did have half of those lightsource problems)
This is a statement to all manchildren who think that objectified women in comics are okay. To those that saw nothing wrong with the fact that this image I linked is a COVER of an OFFICIAL COMIC MADE BY MARVEL, to those who see nothing wrong with how Starfire and Harley-Quinn are being portrayed in the new Under the Red Hood comics by DC, to those that think that every time someone complains about something sexist in a comic, movie, or any other media, it's just "feminazi lesbian bitching".
So, since you guys have -no problem- with famous female characters that have been even used as rolemodels for (mostly female) children and teenagers being completely bastardized and objectified just to please men, then I guess you guys won't have any problem with your favorite superheroes being objectified to please an ever-growing female fandom of the comics, right?
This issue doesn't just affect fans of the characters that are being bastardized, this is a way, way bigger issue. Like it or not, we all have responsibilities when we are part of the media, or even out of it. Even simple statements we say to friends or strangers, we are responsible for what we say and partially what things might happen directly because of that, even though nobody wants to take such responsibility for it.
That being said, constantly objectifying women and not ever letting female characters in general stand in such privileged positions as your male characters in your comics says a clear statement to those reading them: That this is normal, and that women aren't as capable or supposed to be taken as serious as men, and that their value is based on how sexually attractive she is. Because those things are taken as normal in comics (and even in many other media forms).
Now, there's a clear difference between objectifying and having sexually attractive characters - the latter happens with a lot of characters for the sake of selling. Wonder Woman fits a beauty stereotype, and so does Superman. Objectifying is when sexualization goes so much further that it is the main reason the character is there. Many male superheroes -are- handsome and attractive, but is their main characteristic how sexy they might be? Are they mostly there to be wet dreams of a female audience? No. But take most female characters and those answers might actually both be "yes".
