Yoda said it best when he said that fear leads to anger and anger leads to suffering. It is out of fear of something that we resort to violence. Violence is destructive to the harmony that most of us seek to achieve within society and ourselves. Violence also sells video games and movies faster and better than anything except maybe sex.
Humans are a destructive species folks, nothing we can do about it. From the time of Neanderthals to the space age, we were born to destroy everything in our path that doesn’t fit what we like or makes us afraid. What do I think? I think that violent video games and movies are a GOOD thing since they give us an outlet for our destructive tendencies that doesn’t shatter what little harmony we’ve accomplished so far (which is damned little). Can violence in schools be stopped? Sure it can, but very few people have gotten the clue of what really causes it.
