Life is an endless spectrum of dichotomies and paradoxes. The mind can’t handle all the variants. It likes absolutes. So it is wired to be binary and dualistic; to see issues or people as polarities then choose a side. The side we choose often becomes our identity; which informs our beliefs and behaviors. The more strident we are about our “side” the more resistant we are to staying open. This is why I’ve said that ideology is a low form of consciousness.
