Don't bother with him. He is a very simple minded person who doesn't understand the complexities of history. A Useful Idiot some would say.
"In political jargon, a useful idiot is a derogatory term for a person perceived as propagandizing for a cause without fully comprehending the cause's goals, and who is cynically used by the cause's leaders.[1][2] The term was originally used during the Cold War to describe non-communists regarded as susceptible to communist propaganda and manipulation.[1] The term has often been attributed to Vladimir Lenin,[3] but this attribution is unsubstantiated."
