You mentioned that arguing with people on forums is stress relief for you, for most people it isn't, and they'd rather be able to discuss stupid, meaningless things on a forum without having some hot head being an abrasive ass because he disagrees with an opinion they posted.

The term "troll" gets thrown around too often, but this is exactly what makes him a troll. He says stuff just to get a negative reaction so he can be all high and mighty about his opinion truthiness. And then when we call him out on it, either we didn't read all of his post, we didn't understand, or he was making a joke that we didn't get because we need humor transplants.
