Tbf she plays COD on Xbox Live which is known for being played by the kind of twunts who will go out of their way to use offensive language. It is sexist. But it is also racist. Homophobic. Any other ist you can possibly think of in fact. It is at least equal opportunity bigotry.
As for the threats to rape, from what I know of it the word rape is thrown around constantly. They threaten to rape just about anyone, male or female. They also use the word rape to describe certain actions in the game.
Essentially they will pick the words they know are most likely to offend/shock. Unfortunately for female gamers the words that offend/shock the most are related to their sexuality.
What concerns me more than the immature twats on there is that when their behaviour is reported to the mods/companies in charge, the users are rarely banned.
If you contrast it with most MMORPG's, the trolls on there get banned or at least suspended.
Hmm, if you've made it through all that waffle, my point is that women aren't under fire in gaming. Just some games, and they are under the same amount of fire as the next person in those situations. I'm not excusing it, it is obviously wrong, but I can't agree that women are more badly treated.
