Then be a parent and say "No" to Fat Norman. Do your job if you don't want your kids playing those games. Don't ***** and complain about it because you can't do your job as a parent. What you posted so fit the stereotypical mass regurgitated bullshit statement about video games and their "impact".
You and everyone who makes these kind of arguments are always missing the larger point,always blind to the most important aspect of the entire debate. It's not about whether or not the game lets you kill X amount of people, or what it depicts, be it drug use, prostitution, corruption, etc. It's that you simply don't agree with how a person or a group of people chose to express themselves and their creativity through their work in whatever medium of art (be it in a book, TV, movie, video game, sculpture, painting,etc) and because you are so bothered by it, instead of being "normal" and just not participating in reading the book or watching the movie or playing the game, you choose to support ideas that try to govern that content for ALL people, regardless of whether they are a "fan" of it or just indifferent to it. People who are responsible, who are mature enough to separate reality from fiction, who see it as what it is and nothing more. You want to censor and restrain those people who might make that kind of art because you simply don't like it. Nothing more, it's nothing deeper than that.
What are you trying to do? Can you not see the incredible irony in behaving this way in our so called "Land of the Free"?
