"Its like the sex appeal is being removed from all female characters now..."
I've two opposing thoughts on this:
1. I wouldn't call it removing sex appeal, but rather, anything that could be found sexually objectifying. Marvel is trying very hard to cater to non-traditional audiences instead of being the boys club it's always been. (And let's be candid, it largely *has* been a sausage-fest in comicdom.) If anything, they are asking the question: why is it that all sorts of people go to see our movies, but only guys read our comics? What can we do to make ourselves more palatable to female readers? And their answer is to try to improve the writing and make the heroines less eye-candy and more identifiable to young girls. Or conversely, avoid doing what DC did with Starfire: presenting her in the cartoons one way, but then over-sexualizing her in the New 52 relaunch of Red Hood & the Outlaws. (I do find it ironic, however, that many modern feminists have the same attitude and outlook as the Starfire they loudly criticized: "I'm a warrior, an individual, and I'll do whatever I want, including having sex with whomever I want. No one owns me and no one will tell me how to live my life." But since this version of Starfire was considered sexually objectified for the benefit of men, it was demonized by feminists instead of appreciated for what it was.)
2. Having said that, I DO believe that all the traditional bastions of "boys clubs" - from gaming, to comics, to pr0n, to even the Boy Scouts - are under intense pressure to stop being "for" boys and men, as if the idea of letting men have something to themselves is patently offensive to modern feminism. (Guys, don't feel like you're being singled-out; modern feminism gives the same amount of ire and indignation to women who choose to embrace historical gender roles or ideals.) And it will continue only as long as organizations feel more threatened by being castigated on social media as being "anti-woman" than they feel threatened by the lack of revenue driven by men voting with their wallets. This is not the first time feminists, en masse, have tried to re-order society to meet their sensibilities, it's just the first time they've tried it in the era of social media, so it seems much more intense.
