Any system that tells deeply hateful and impoverished city folks that they are not just allowed bit morally obligated to commit atrocities against people they resent and their property, well, that's a pretty damn easy sell.
You're muddying the waters on this issue. Communism (and I'll gladly designate that as a general umbrella term for any and all petty distinctions you want to make) is a deadly, genocidal ideology of resentment, vengeance, and destruction, just like German National Socialism was. Communism is a set of systems that require large-scale slavery in order to function.
Do you or do you not think Communism is destructive? Would you or would you not condemn Communists at the same level as Nazis?
And, to anticipate, if you want to claim "that wasn't real communism," remind me to never make you the dictator.
