I'd rather just play the games rather than listen to some self-proclaimed expert saying it'll make me shoot my entire college. However if one bans games, one should also ban ALL forms of media. Everything from books to films are specifically made to manipulate you emotionally, whether that's anger, feeling of sadness etc. Yes, you are being controlled by not just the government, but by the authors, the musicians and the artists.
For me it's like this when it comes to games:
Killing a person in a game = I feel nothing, since I know it's only a bunch of pixels/wireframe with a texture slapped onto it. Sometimes it may be even funny. It's even less worse than dismantling my PC or breaking something.
Killing a person IRL = Scared shitless and feeling of guilt since I know said person was real.
