Outwardly, most people who know me see a somewhat lackadaisical, laid back dude who tends to go with the flow more often than not. I never said I was afraid, I just tend to be a lot more aware of my surrounding environment than people realize. For instance, I can be in conversation with someone and appear detached, yet repeat everything back to the other person. This happens a lot with my wife--she'll yell at me for not listening, but then I'll repeat what she just said. "Oh...well you didn't look like you were paying attention"
I'm not saying you're wrong and I do appreciate your analysis, btw.
Another thing--if and when I act warm and diplomatic toward people, its not defensively. That's always been my natural way of interacting with people, although there is a slightly cold, calculated side to me that also shows often--I am a walking contradiction in that regard.
I also wouldn't say aggression comes naturally to me. I can be forceful and persuasive when I need to, but usually aggression, whether physical or verbal, is not my primary approach to people and the world around me. Take charge? Yes, as I said earlier, I can and will, but usually only when no one else has stepped up to lead. I'd still much rather say in the background doing my own thing.
I don't think 6 is my core, but I wouldn't rule it out completely.
