There's something to this. Online PC gaming communities can be really problematic, but online console gamers tend to be even worse. I think it's the younger age and lower bar to entry.
The CS 1.6 community could be pretty toxic circa 2007. At least in France.
Toxic does not even begin to describe it. The rampant bullying and misogyny, the stupid machismo... It completely turned me away from pvp and competitive play.
