It seems to me that conservatives are motivated by strong moral issues and liberals by reason and rationality. If the outward is motivated by the inner it would imply that conservatives are concerned with appearing moral and liberals as being smart. That seems to fit with the stereotype that conservatives are stupid and liberals are evil. But what would cause such a motivation.....why the need to appear a certain way......where's the ego satisfaction, what is being protected, what illusion maintained.
If we hate ourselves,. as I have long suggested, but each in different ways, what could categorize us into two broad political groups. As I have also suggested we were enculturated, programmed to fit in, trained how to behave to make us safe from criticism, and this was done by criticism itself, being put down for being out of line, non=conforming in some way. There are two common ways to do this. One is to strike the fear of God into we children, to make us fear moral deviation, and another is to call us stupid for bad behavior. We are tremendously competitive, in my opinion, as to who is smart and who is good. Now if external emphasis is on one or the other the emotional need arises out of the opposite feeling, either that we are really evil, which we would project onto others as a defense, or that we are really stupid, which we would want to tag others with. Meanwhile, our egos would provide us with a sense that we are good people, an immunity to moral shame, or that we are smart and rational. And of course, we might even be driven to really be those things in practice,
