years of being a loser, demascunilized or whatever you call it, not being able to become the man society expects you, no way to let steam except for furious masturbation, gorevideos & video games, no sex, no sports, no confidence, no friends, self hate, being a NUTJOB, no social skills..., being a NUTJOB... & easy access to guns - the great equalizer, the tool that let's you become god for a moment. let that cook for a 2 or 3 decades and you got yourself a nice shooter who wants payback on this society who ruined his life...
btw it's not only whites, but asians too - but asians run around and stab people because it's harder to get gun over there
