The Liberated Territories wrote:"But they had good intentions" isn't an argument. Communist regimes killed millions of their own people. Not due to war, or ethnic hatred, or anything, but because they disagreed with communism.
And Nazis killed millions of their own people. They did it because of war, ethnic hatred, and because they disagreed with Nazism. That Communists aren't angling for extermination isn't an excuse for their mass-murder - but if you're asking me "Which mass-murderer is worse", my answer is 'Nazis'. Every time. The only reason the commies have a higher kill count is because they were more widespread and longer-lived.
