Marx wasn't a Marxist (he said it himself) and the typical "communist" countries like China, the USSR, North Korea, ect. are (or were) all "red fascist" regimes. It's silly to look at the death toll and choose the one "ideology" which killed more. As CPig said, both options are the same, if you read Marx you'd know that the "communism" as it was practiced has nothing to do with actual communism. It was only a cover and a tool for the bolsheviks to rise to power.
