First, if you are being bullied or harassed, you need to report that. Adults doing that to kids especially make me sick. No reason for that to go on. Kids are kids, they are still developing and they are all over the place. Here is my take on the situation though: If I get into a match with the 12 year old kid who is swearing constantly at the game, yelling at their younger brother while fighting off their mom about having to take the trash out, they get booted or I leave. If they want to be treated like adults, they need to act like them, or at least have respect and realize they are not the center of the universe or the only one who knows how to play the game. I have played with very respectful kids, and thats great. I will help anyone out that I can. Just need to have respect for others, especially adults who are trying to help them. I don't mind mistakes either, and am a very patient person, but there are limits to that. Stop trying and start throwing tantrums, you are gone.
