7. I absolutely think we there are born liberals and born conservatives. I think evolution 'created' a balance

in the population between 'cooperators' (us) and 'competitors' (them). That's why there's liberals and conservatives in every culture, probably in roughly similar %'s. It's beneficial for the species survival to have that balance of temperaments. If the population is too conservative you kill each other, and if too liberal, you get killed by others, that kind of thing.

I bet if you studied chimps (and knew how to study for it) you'd find the same going on. Bonobo's too. Although Chimps are way more like conservatives, and Bonobos way more like liberals overall.
