I knew that the human mind is not as biologically inclined to be rational as it is to survive. That even when faced with clear evidence to the contrary, if a person’s belief system (say that black people are evil race baiting crybaby animals) is rooted in their identity, any challenge to their opinion feels like a threat to their very lives. An ancient and impenetrable aggression takes over that can not be reasoned with, only shut out or ignored.
So true. No one should waste time trying.
