He is handicapped because he knows it is pointless but he thinks if he stops we dominated him. He basically thinks he is at war with everyone by doing it. That is why it annoys me, I could really care less about the small text itself.
People do pointless things everyday, does that make them handicapped. I'm sure you've done some pointless things in your lifetime, are you handicapped? Maybe he just likes doing it to be distinguished from others. What is wrong with that? It is his choice.
In reference to the "at war with everyone" nonsense, that just seems like a poorly obtained, half-assed accusation. I would like to see some sort of valid evidence backing up your instigation.
