Genghis Khan. Of the three mentioned, I don't remember which more responsible for the most total deaths, but I'm fairly sure that Stalin was the most "efficient" butcher of the three. Though in terms of efficiency, there was that dumb-ass ruler in Paraguay who managed to get 90% of the male population killed, he probably deserves at least a dishonorable mention.
Is the world's greatest mass murderer Hitler, Stalin or Mao?
Whereas Hitler managed to kill about ten million of his own people over about seven years, the marxists, led by Stalin and Mao managed to kill about one hundred million of their own people over seventy years.
And it is important to remember that it was not the enemy they killed but their own people who were helpless and dependent on them.
Stalin notched up about twenty million, but Mao topped them all with about eighty million.
And for those of you who would like to read the documentation and the exact figurers, you can find them in, "The Black Book of Communism", written and collated by a group of left-wing French historians.
So it is the marxist Mao who is the world's greatest mass murderer.
Does this matter today?
Yes, because today the Marxists have joined the Islamists in their jihad of murder, intimidation and propaganda.
Yea, but the Chinese and the Russians don't carry a lot of water in Hollywood so who cares? The Chinese especially got piled up like firewood by the Japanese. Then the Chinese Communists ran through and piled up some more. Human beings are animals to one another.
This world is drenched in blood. How many people and cultures have been ground into dust? All forgotten.
The only consolation is that all men die and all people are forgotten, in the end.
"Create like a god, command like a king, work like a slave."
Let's never forget the little Hitlers of the world.
