I still don't think it's reasonable to describe "totalitarian dictatorships" as "communism".
If I take a bunch of people hostage at the local school and tell the police that I am holding a "school board meeting" that don't make it so.
I'm under the impression this is the only real way communism can be done - with laws (force) that take away private ownership and a government that attempts to institute communist policies.
Yes, and it's a largely incoherent idea.
But at the minimum, I have my doubts that the prominent examples of dictators living in palaces and enriching a small elite while peasants starve is really trying their best to live up to the ideal.
Eventually, people resist having their property and resources taken away from them and then the state turns to violence to pull it off. Dekulakization.
