Recently my Xbox 360 died, and so I decided to try some new things, like going out with friends. The sun burnt me at first, but then I realized that there's a world where people can't scream into your ear that your a fag, or a cheater, or a 'haxxor'. I realized that even if people actually do this, I can punch them in the great outdoors. And so I find myself playing less and less video games, and actually enjoying my life.
My point is, it sucks. So just get away from gaming for a couple weeks or something. It actually does feel really awesome. And I'm not being patronizing or sarcastic, I really am serious. I find myself enjoying life more, and I've all but forgotten about online douchery.
But if you can't get away from gaming, just mute everyone. Mute all the voices in the game. Problem solved.
