Commie thugs have pulled the wool over the eyes of their base... You're right - the biggest advantage we had over Hitler was his evil was so over the top, so horrible, so inhuman - that even hearing his name said out loud is a creepy experience all these decades later. Hitler defines the concept of evil. The left was able to sugarcoat Stalin... his evil is confused and mixed up with the stupidest political philosophy known to mankind: Marxism... That game changer allowe him the intercultural cover of two bit power grubbing phonies...
The Nazis also kept good records, and the Allies documented the liberation of the camps. The Left loves communism, and hates fascism. The commies won. Joe McCarthy is treated as a bigger threat that the USSR or traitors were.
