I'd say there are for more anti social, awkward/self pitying dudes on 4Chan than psychopaths. They aren't united with that GamerGate shit, there are people on both sides. Racist as hell language, yeah, that's definitely on 4chan.
The only difference between 4Chan and Gaf is there is no filter. Psychopaths can't flourish on NeoGaf? One of the has been mods assaulted his mom because of fucking South Park.

Kingii or whatever his name is joked about around these parts, dude says by the time he's 30 and doesn't get laid, hes going to kill himself or some shit.
Users of 4chan have done heinous shit, but there are a lot of people that make dumb meme posts and shoot the shit.
