Dobson had neither male nor female friends growing up, so every man is a bully and every woman is put on a pedestral to be worhsipped. It's much like OPL with his attitude, though Dobson lacks the galpals.
His internet behaviour reinforces this childish black-and-white worldview, especially since Dobson is the kind of asshole that's controversial for being controversial's sake, being a contrarian asshole, insulting people left and right and then turning around and yelling "why is everybody so meeeeeeaaaaaan to me?"
And I wouldn't even blame his short fused nature on the decade of trolling... that trolling was a direct result of Dobson's shitty character and fucked up attitude to begin with.
I mean, his "Wii > everything" Not-Jon-Arbuckle and Marsupiheathcliffe comic was nothing but Dobby trying to troll XBox and PS4 players and wondering when he got heat for his childish, uninformed, petty views.
That's why I never felt any pity for Dobson, even when he was sprayed with water. You simply don't poke the hornets nest on a daily basis.
