Do you believe that violence in media promotes violence in real life? Does media reflect cultural values or can it actively reshape them?
The media shows violence because that's what people are attracted to. Everybody is and that's nothing new. Shakespeare has violence in a lot of his plays, because people are fascinated by it. Something draws us to watch it happen, perhaps awe, perhaps terror. The violence in media does not affect violence in reality. There's no hard evidence to suggest that it does. There are fun facts like the national crime rate decreasing ever since Grand Theft Auto and its sequels came out. A lot of us grew up with Power Rangers, but you don't see us going around karate kicking everything in sight.
