Cognitive Dissonance is very real and dangerous. The root cause is the attachment to a belief system that ego doesn't let go. Anything that shakes that belief system, the ego treats it as danger to its existence and tries to eliminate it at any costs. It does not want to let go of that attachment because that would mean diminishing of the identity that was formed from decades, especially since childhood. The child still living its days in the adult throws all sorts of tantrums, fights even up to eliminating anything/anyone contradicting what the child had been attached to. Apparently "open mindedness" has an individual limit where letting go of beliefs causes pain.
