I'm tired of people like this promoting this myth that if a medium's target audience is men, then it must be inherently sexist.
I don't believe you can stereotype "gamers" anymore than that. The writer is quick to label the video game industry as sexist and elitist (comparing them to the tea-party so you'll get on board for sure) so they can write it off later as "capitalism's" fault.
I don't see how this defends anyone, they completely bash the industry and the fanbase and blame it on a mysterious minority that made them believe all of their widely unpopular opinions. It obvious that internet trolls or flamers are just dumb kids who say whatever for shits and giggles, and have nothing to do with video game culture
