I think that the "12 year-olds on NS" stereotype is overblown. I find it hard to believe that many of the annoying people that I've see posting on here are 12. I'm willing to bet the percentage of NS'ers who are 12 is very low. The real shit-talkers are the 15, 16, and 17 year-old middle school and early high school kids.
But, this thread is shit anyway since you yourself are talking shit by making it.
