he's got that much self belief/arrogance
I'm guessing it's more a case of trying out a cool new cocky online personality, then realising he can't take the heat.
still, all he did was make a few silly and annoying comments on a website about a comic - it's hardly Dahmer and Gein territory. I wouldn't wish failure on him for that. And once again, a few flaws aside, I think his stuff is alright.
