Video games & Bullying

Many think that video games lead to bullying due to the violence which many video games include. It seems that enacting this violence in a virtual world will lead to violence in the real world. Such believers use events like the Columbine shooting as proof of such causal relations. But from my view, it seems that violence is a part of human nature. One will either use the video game as an outlet for violence or a propellant for violence depending on inherent nature. It seems to me that usually video games bring together people who may be out bullying otherwise. Virtual R.P.G's allows player to form relationships that would otherwise be nonexistent, a way for people who may be "socially awkward" to excel in an area which may not be available to them in the real world.
