There are more than one “gamer” culture. Not all “gamers” are racist FPS players and not all racist FPS players either agree or understand the message carried by their games for all that matter. I think that we should denounce and explain the worst aspects of gaming culture and not denounce gaming as a whole as something bad with no value. Otherwise this is counter-productive given the cultural importance video games have took.
And what do you base yourself to say that? You seem very prejudiced toward the hobby of video games.
