He be trollin'
But seriously, the problem isn't that this guys is either a blatant idiot, or a real life troll, it's that people will LISTEN to him. I guarantee that some parents out there tried what he asked and took the controller from their kids. Dependant on age I assume, those kids probably got pretty pissed.
You hear so often of these crackpots stepping up to the world stage and making outrageous claims like, Video Games are like doing lines of Cocaine, or Bulletstorm will make you a Rapist. But there is rarely debate on a mass media level, just slander. Games need a better voice then the internet, there needs to be a counter-call from a mass media level, some level of education against this kind of moral tripe. I think Publishers, the ESA, and various other groups need to stop being reactionary in their dealings with these people. Do you think a true voice of the gamer's side will rebuke this anywhere other then the internet? Probably not, but I think someone that people will respect, and will listen to, needs to rebuke these claims! A poster boy for gaming, an expert on our side. So that people can actually hear this other side of the debate.
Challenge these people who make these claims in a civil manor on a mass media level. Make them come to call for what they say and beat their argument, that is how we are finally going to show people with these ridiculous claims that they are wrong.
