A lot of my posts are spurred by conversations. This one began with the discussions revolving around Grand Theft Auto 4 and the continuing debate about whether violent video games make violent people. Some research suggests maybe there's a link. Other research concludes there's not, or at least nothing very strong.
Ending violence involves finding the correct method. The inherent fallacy about gun banning is that somehow you can prevent people from harming one another by removing one of the tools they sometimes use for that purpose. It's no surprise that approach doesn't achieve the desired result. You must instead work to change the violent nature of humanity. Then it won't matter what tools are available. So long as we are violent by nature, taking away any particular implement or class of implements won't help. There are plenty of rocks and sticks in the world.
Based on that idea, we should probably ban all violent movies and video games. There's a problem with that, however. There are people in the world who train for violence besides the U.S. How did peaceful peoples do against the Spartans? Not so well. Does that mean peace shouldn't be a goal? Of course not. It just means we're not there as a species yet. Everybody has to agree this is a good idea and work toward it or else peaceful peoples, happy or even smug in their superior position, will always be slaughtered or subjugated by those who train for violence. Long term, that's not a successful strategy.
There's a middle ground. We still play cowboys and Indians. We still play cops and robbers. We even have violent movies and video games, but we also work hard to establish a strong sense of reality vs. fantasy and to instill the idea that violence is only an option in self defense when others initiate it. Training for war and never having to go to war is much better than failing to train and being overrun and enslaved. If everyone did that, there would come a time when even the training would no longer be necessary, because harming another person would become unthinkable.
I hope we get there.
