I don't think it's JUST that, people with an agenda will always cherry-pick, whether from a game, a movie or a song. Games are probably the easiest targets, because to most of the classical extremist groups it will be the only major medium they have no personal experience with - and thus the one they fear the most. Another thing about people with agendas - they often try to pass themselves off as 'journalists', a title that some people take as respectable, even if there are absolutely no qualifications for it (at least around here!)
