Gentlemen:
Here's an idea.
Next time you see a video game female posed in a particularly sexualised way, try imitating that pose yourself. Stick your arse out, arch your back, twist, bend over, whatever.
See how effing uncomfortable, impractical and absurd you feel. Do you feel embarassed or stupid, going into those poses that are solely there for sexual titillation? That is how uncomfortable, impractical and absurd most women feel in those poses. That is how little those games think of us. That is what they tell us we are worth.
If there is ever a time you want to say "but video games are supposed to be fun", ask yourself, "fun for whom, exactly?"
If you want to enjoy sexist shite, enjoy sexist shite, but don't pretend it's not sexist shite and don't tell anyone who is bothered by it that their feelings aren't valid.
