When I say either side, I'm not talking about right or left. There are people who believe things they are told, and there are people who come to their own conclusions. Many conclusions are ugly, or at least seem very ugly without an understanding of where someone is coming from.

Specifically, ideologies you listed like that of the Nazis, Misogynists, or racists are very reactionary beliefs. The scary truth is that there is no difference between the humans living in Nazi Germany and you and me. If you cannot understand how someone got to a conclusion, you will never be able to change their mind.

Old Ayn Rand quote - "Contradictions do not exist. Whenever you think that you are facing a contradiction, check your premises. You will find that one of them is wrong."
