The problem is the Communists have never been held accountable. That is true of the Soviet Union, China, Cambodia, etc. The left screams Nazis but doesn’t understand the Communist were worse.
The Communists were perceived as being for the “downtrodden”, while the Nazis were all about the “Master Race”.
But what’s funny is that Stalin governed more like Hitler, and in the Soviet Union, the Russians were the “Master Race”, despite Stalin and his cronies not being ethnic Russians. Stalin even rehabilited Czarist heroes, like Ivan The Terrible and Aleksandr Nevsky.
That’s because the lefties ARE commies.
