What about violent books, conversations, thoughts, and lectures at school? (Have you ever read a history book? They're twice as violent as Grand Theft Auto.)
Honestly far more disturbing than any game I have ever seen.
It's a familiar horse to beat, this NEW media is special, and different and scary.
It happened with jazz, rock&roll, comic books, movies, novels, heavy metal, many scapegoat has met the whip of the righteously ignorant. It's always been a meaningless argument, totally void of scientific fact.
Were there wars before fiction? Was there crime before video games?
