I am using Peterson's psychological definition of liberal and conservative temperaments, which I think holds regardless of the current manifestations of (and abuses of) the terms. He has theorized that the core political, and in fact philosophical and perhaps even more deeply, religious, battle in the west is between people who think there should be borders (physical, e.g. between nations, conceptual, e.g. between sexes, etc.) and those who do not, which revolves around these two psychological axes.

Interesting to think about.
