I don't think this is simply an issue based around a certain genre and small community of gamers, this has become a general problem over the years. From Arcade to PC and now Console, the whole community within gaming has gone markedly down hill, ever since the ability to communicate online during play was enabled. Even on less competitive arenas, such as unranked online play, the whole attitude stinks to high heaven.
I've lost count of the times I've beaten a guy or been beaten and got a microphone tirade or a message with text / voice, coating me off with various expletives featured in Shakespeare's famous work "How To Be A Cunt And Influence People"
Then you get the whole hitting on the female player in the room, because apparently in some bullshit unwritten rule, that's okay too, they expect and want it.
Couple this with the self-entitlement of being able to say what you wish, there seems to be an ever growing mass of Racists and Misogynists playing videogames of late, and its these same pricks that will stop gaming rising above its "immature" status in the eyes of the non-gaming world. I've been gaming for 30 years and I have to say, I hate what my community has become.
