Gamers Against Bigotry →

wilwheaton:

THE PLEDGE: As a gamer, I realize I contribute to an incredibly diverse social network of gamers around the world, and that my actions have the ability to impact others. In effort to make a positive impact, and to create a community that is welcoming to all, I pledge to not use bigoted language while gaming, online and otherwise. Bigoted language includes, but is not limited to, slurs based on race, ethnicity, gender, sexual orientation, and disability.

In other words, Don’t be a Dick.
