This should have ended the thread right there. Some of the things posted were rather entertaining. Not on a funny comedian level, but on the side of "man, it sounds so outrageously ignorant that it's kind of funny". It's tough enough to debate with some people, but what makes it interesting is it's the mentally diseased. That's not to disrespect in anyway. Maybe he has incredible paranoia of others? Maybe he's incapable of thinking logically with some issues? Who knows?
Going down the route of "defending genuinely shite posters because they're mentally ill" hasn't worked before (see: Bad Blood) and it won't work now.
