Many people still think of boys (and men) when they think about computer and video games like the Half-Life and Halo series of games, World of Warcraft, and games in the Mario and Zelda universes. But more and more girls (and women) are interested in and very good at playing computer and video games. Sadly however, in the online gaming universe, people are often harassed, threatened, and bullied because of their user names, avatars, or occasionally voices, and girls face a disproportionate amount of harassment. Though it's unlikely female gamers would face the same volume of harassment from their persecutors face-to-face (as opposed to online), girls are generally not as prevalent in Role-Playing Games (RPGs) like Dungeons and Dragons as boys, and are often actively excluded (I write from personal experience here).
In an effort to change attitudes, a group of girls, all gamers, created a video about who and what they are and are not, as well as how they'd like to be seen. Not only a message to stop asking female gamers if they'd like to know how big someones' sword is, but to stop bullying anyone who isn't a stereotypical "gamer."
