Too many of your peers have left a bad impression on many. I hate most kids in this community. That being said I do game with my clan mates 15 year old son and besides a superman complex, he's quite skilled and mature for his age. But unfortunately there's a list of things that 18- people have done to make most adults steer clear of your age group. Most of the ones that hardcore make fun of you are probably kids who aren't even that much older than you. Ignore them as they think that because their voices drop slightly and they've officially grown their second pube, that makes them so much more mature than you. Find a clan with people in your age demographic and dont run with randoms. Good luck man :)
