It's ironic how true personalities emerge when covered by the blanket of annonimity. If someone isn't a retarded troll in real life but is dedicated to being one online, probably out of a sick fascination with shadenfreude, then he IS a retarded troll. The only thing keeping him from doing it in RL is consequences that he doesn't face on the net. I'd say online behaviour is strangely more honest than RL behaviour in many cases.
