In general, most annoying players behave immaturely. Most (but not all) immature people are young. Ergo, most annoying players are young. Yes, there are mature kids, and immature teens/adults. But statistically, the younger someone is, the less mature he is. This is a proven fact. People who generalize about all of the younger players being immature ought to take a good look at themselves. This is not a particularly difficult concept to understand, certainly not one that deserves five pages of flaming and ranting.
