This guy is not just a troll. When a troll exhibits this level of "EPIC FAIL" you have to assume they are mildly retarded or just plain insane. A good troll would exhibit skillful usage of English to entice people to bite.
In fact, everybody knows that a good flame-war is fun from time to time. Trolling to a small degree is a pretty natural thing to do online, where anonymity and lack of consequences can make an argument more exaggerated/fun.
