Males are constantly posed in sexual ways. It's sexual when women wear revealing clothing but not when men with bulging muscles run around with nothing but a loin cloth?
His point, again, was about the amount of personality portrayed. He says they look as though they're posing in a mirror. Every image I posted shows a female character whose personality is in some way being shown through their pose. Be it their determination, bravery, despair, gentleness, whatever you like. If you look at Harley there's certainly a bit of an edge of sexiness there, but if you know the character Harley Quinn you'll know that's a big part of her personality. She's a flirty violent psychopath.
And I don't know what video games you're playing, but I don't generally see insanely revealing outfits on women outside of JRPGs and fighting games. In the vast majority of the games I have the women are dressed basically the same as the men. Neither modern tactical armor nor medieval plate mail show much cleavage.
But, again, even if the majority of characters were sexualized, I wouldn't really see that as a problem. Sex sells and there's literally nothing wrong with it. Sex is great. Sexuality is great.
If something is heavily laced with female sexuality and that really turns you off, it literally wasn't made for you.
I love the movie Secretary because I think BDSM is really hot. If you're not into BDSM you may find it strange and creepy. That doesn't mean Secretary shouldn't have been made or that there's a problem with movies like Secretary existing, it means that you personally shouldn't buy or rent Secretary.
I like Day Z because it's ruthless. Lots of people don't like it because dying and losing all their gear bothers them. Should Day Z cease to exist or become easier to cater to the people who don't like it for what it is?
Constantly catering to the most common denominator is boring and produces boring art and entertainment. If you don't see the kinds of video games you want, there's an easy solution. Make them or fund them.
