I think what you are talking about is not Communism the subject as outlined in The Manifesto and Das Kapital, but Communism the movement as laid out by Trotsky and Lenin and then Stalin. Its a fine line, I grant you. But the control of population and how to motivate them and the rest of the diabolical mechanisms - the secret police, the reporting, the attacking of "divergents" lying to advance the cause - well that has a different history going back probably before the inquisition. Religious fanaticism spawned the concept that a "higher cause" could trump doing right in the here and now and every cult leader has used it ruthlessly - from Stalin to Mao to Franco to Hitler and Kim Jong Il and cult leaders like Hubbard and Jones and Loyola and even such organizations as Amway Herbalife Arbonne and the rest all use totalitarian control. All will lie to forward their agenda, all will put everything below the advance of the agenda - family, allies, NOTHING is as important as the cause.
