Again, that is all stuff that rolls over from being either an adult or teen, its a person personality and how they are raised. I was playing table top since 13-14 and most players enjoyed my company because we would talk about tactics, have good sportsmen ship, complemented each others great play, etc. Magic breeds a certain group, while in my LGS I over heard an older guy just trying to BS rules (I don't know them but I could tell it was not the correct way due to how every one was reacting and how he would react when they would bring up the rulebook/FAQs) so magic is a bad pool to pick from. I've had people just flip out they were losing to a younger player as well. Then I've had a really shy teenager that started to play and he actually opened up while playing, literally the first time I had ever seen him so happy and animated which that alone made that game enjoyable. So, don't just generalize the whole group of players because you've had a bad experience or two, because I've had my fair share from both groups and both can be great players but each have their problem cases.
Gamers are gamers, don't try to invalidate someone's experience because they play a different game. My experience is from the last 20+ years playing various games ( including D&D, MTG, WoW:TCG, Star Wars CCG, Warhammer Fantasy/40k, Warmachine, Firestorm Armada, and Xwing just to name a few).
This is also coming from experience From small town LGS, to Games Workshop Hobby Centers, Fantasy Flight Game's own store in Roseville, MN, GenCon general gaming sessions, and beer/pretzel games in a friend's basement. In multiple states from the midwest to the east/west coat (thank you military for moving me everywhere!).
Young children + games that require anything more than the most basic amounts of attention tend to = a meltdown and frustrating session/environment for older or more mature gamers.
Go ask any LGS owner what demographic causes them the most stress/drama. I'll bet they respond that it's the 14 and under crowd.
