what MAKES people become liberalish or conservatish

Two basic conflicting desires in the primate mind, Bill: the desire to live your own life the way you want to, and the desire to make other people live their lives the way you want them to. The former is the individualist instinct, and expresses itself in the politics of the right, and the latter is the collectivist instinct, and expresses itself in the politics of the left. The conflict between those two desires is comprised in the dynamic of all primate societies.
