It is clear he has mental problems....everyone would agree on that.
This is the difference between Joe and Acebb. Joe knows he's an obsessed psycho and relishes in the fact of being someone on the outside of the educated/mainstream community because it makes him feel like he belongs. But he knows he's a psycho and a troll.
Acebb is the opposite. He wants to be intelligent and educated and probably grew up with a lot of retards that made him feel like he was intelligent. Then he came and met us and can't handle the fact that he is a retard. That's why he won't admit he's ever wrong, he'll make shit up, he'll backtrack on things he obviously said. The dude has serious mental problems and most likely is a loser in real life trying to overcompensate that and take it out on real educated people.
So they act the same but for different reasons.
