Trust, I don't have time for a long reply, but I would like to point out that this is not a highschool debate. People should not approach their lives as though they're in a highschool debate. The purpose of a high-school debate is just to win; the only reason for considering or thinking about the other person's viewpoint is to see how you can discredit it. It is an exercise in persuasion.
In real life, you should be happy to admit when you are wrong, because then you have learned something.
Well, let's see. Instincts, we don't really have to act on our gut feeling, we're reasonable, etc. We are completely different at the core.
We're reasonable? Look at you? Look at what humans are doing to the world. We're completely different at the core? Good job supporting that controversial point. I particularly like your touch; how you argue by either stating very questionable propositions as obvious facts -- proof of your thoughtlessness -- and when that fails you become aggressive: first you are actively aggressive, and then passive aggressive.
