Want to see less sexism in games? Stop buying shallow and commercialized titles and support developers who actually try to express their ideas via the medium. Seriously.

I'm not saying you should switch to a different kind of games and ignore the trends in the rest of them, but I see that a lot of people decrying "sex and violence" in various types of media are also validating the exact same works that are fundamentally based on sex and violence. That doesn't make sense.
