You can say I’m wrong but that hardly makes me wrong.
If people who commit mass murders are gamers, how can you dismiss the cause and effect so quickly?
I will continue to believe that people who are attracted to violent video games have mental health issues.
If people who commit mass murders use guns, how can you dismiss the need to ban them?
More directly, I've been a gamer my entire life, so have my friends. So far, zero mass murders or other psychotic behaviors among us. The gaming community in general is quite large, so of course you're going to find people who engage in less-than-stellar behavior.
There were psychotic people long before video games, too. It's a convenient excuse, that's all.
