I'm almost positive the majority of this community is under the age of 17, and I might get flamed for this but, I believe kids are becoming more socially detached because of video games.
Violent video games promote violence and defiance and I think that's a reason why we see lots of kids talking trash on their mics and threating people like they're going to do something about it to shut up another player. Sides, it's sad really, go play sports while you're still in High school. Take advantage of what time you have during those years, those years are the most memorable, and It's no wonder why so many kids are obese and act like straight up douchebags over the internet. It's mainly due to lack of exercise and enormous amounts of time being spent playing video games with a false sense of hope that they'll be a MLG player.
This statement isn't meant to generalize every underage kid but most of them sure act like this and look like this.
