Granted, the difference isn't much in terms of human rights.
I don't have the reference handy, but I remember reading about a priest who had the dubious distinction of having survived both a Nazi concentration camp as well as a Communist concentration camp. In his opinion, the Communist camp was worse. In addition to the hard labor, other physical hardships, and the ever-present threat of death, the Communists added brainwashing. “At least the Germans didn't try turning you into a Nazi.”
Don't forget. Cuba and Vietnam have the same system in operation. Ask anyone in the exile communities in the United States.
