So the tens of millions of people that died under communism were all landlords? Wow, what are the chances of that

Communism is a bit different than what those “communist” countries had. If anything it was socialism, but that still doesn’t fit completely. These “communist” countries are just one-party states in which the government controls the economy. The idea of putting the working class in power is useless if you create a government that can make decisions against the opinions of the working class. Socialist one-party state ≠ Communist democracy

Do you have a real-world example of a successful communist state? Because you may not like it, but those “communist” countries are humanities best attempts at enacting communism and they resulted in millions of people dying.
