I'm actually interested in human behavior. That's pretty much my whole interest in politics. I have the same interest in celebrity worship/hate and religion, it's just that politics is what comes up here most often. And I don't get "emotionally" involved, I get frustrated with the human condition.
I avoid talking politics in my real life - it's not like I'm at dinner with a friend raving about that crap. I actually have a real life that you wouldn't know about considering you're a stranger on the internet.
Get me started on the moron characters on Grey's Anatomy and I'll talk your ear off.
