Good historians are extremely cautious about comparing problems–even very serious ones–to Nazism. Claiming that someone is “like Hitler” or “as bad as Hitler” cannot be done lightly. The enormity of the crimes committed by fascists in Europe before and during WWII is so overpowering that a slipshod or weak comparison diminishes both the horror of the Nazis and the credibility of the warning one is trying to raise in the present day.
