I've noticed this in gaming communities where I've had the interesting perspective of being on both sides of a fence and watch the criticisms that pass over it.
There's mature and calm people on the violent gaming side, absolutely. And they are usually adults with families and a job and such. But there's a lot of young people that love to spew vitriol, especially at the non-violent gamers, like "that game is fucking gay! why would you play it?"
Interestingly it doesn't usually go the other way over the fence, unless it's from people who play both sides but tend to the violent side.
There definitely are people who cant contain their aggression and playing at imaginary aggression stokes them up, definitely, I hate that when I see it BTW, the use of the word "gay" in that prejorative sense and the association of non-aggressive gaming or pass times with homosexuality.
