I'm not "that guy," but I'll be whoever and however I want to be. I'm the guy who knows the difference between what I know and what I believe, and I place a higher value on what I know than what I believe.
I occasionally have, at the most, a mild emotional response to discussions here. I guess that's why it surprises me when people have strong emotional reactions in a post. It's just differing ideas, opinions and preferences as far as I'm concerned. I don't take any of it personally.
