Its just what some people enjoy doing. I enjoy it myself in much smaller doses than he does. But in the past I've had week+ long arguments with him about dumb shit.

Heck, I did the gay little KIA "summit" with him and I can say for certain his stubborn bullheadedness is the trait that takes priority over everything else. He will argue until he is dead on a topic if he is convinced he is right and you aren't relenting.

But that's also why I know he doesn't have ulterior motives. He is a consistent man across nearly a decade now, for better and worse.
