First, read this article.

Now, on to my arguments for why such a labelling system is a joke and the problems with their proposal here.

1. Violent movies have been linked to increased aggression in the past, yet they bear no warning label.
2. Oftentimes, a person who is already aggressive can be drawn towards violent video games because they already have violent tendencies. Their violent tendencies are not necessarily caused by violence in video games.
3. There is no hard scientific evidence that violent video games increase aggression in the players. As such, putting a warning that there is a link means you’re putting out a health warning on something that scientists don’t even agree upon.

This kind of stuff irks me to no end. I am so endlessly sick of people trying to blame video games for society’s woes. Makes me sick. I watched violent movies and have played violent video games both since I was about 6, and there’s nothing overly violent about me. You just need good parenting, that’s all.

This all probably stems from this case, among others.
