Repost all you like. It's still not a study. Hell, it doesn't even attempt to draw conclusions.
No, no, you wanted a discussion of the topic, and I'm discussing it. Unless you really meant "does sexism exist in games, and are games aimed primarily at male gamers?" In which case, yes. I guess we're done here.
On the other hand, if you want to know what should be done about it: stop buying the games and let the publishers know why. Until it's more profitable for them to remove the sexism than to leave it in place, you're just pissing in the ocean.
