The biggest mass murderer in history was Genghis Khan. His reign of terror purportedly decimated 30 to 40 million people.
Since the majority of people he killed were illiterate, there is really no accurate number of the amount of people his "horde" killed. His wholesale slaughter set back the Asian continent's growth and development for CENTURIES.
He named it: MONGOLIAN HORDE.
There hasn't been his equal in wholesale murder since.
WRONG. The biggest mass murderers of people occurred in China, in the 20th century, under Mao Tse Tung. Chairman Mao and his communists killed 70 million Chinese. Communists [and National Socialists] make Genghis Khan look like a piker in comparison with their body counts.
Nevertheless, What does Genghis Khan have to do with Margret Sanger and eugenics and Planned Parenthood? I'm saying that there is a great link to the social Darwinism practiced by mass killers. They all believe they are “improving” the human race by killing off the unfit, infirm, or political opposition. The difference is the killers can smugly justify their deeds but their victims aren't around to object.
I’m pretty sure Chairman Mao (y’sh”v!) gave Genghis Khan a run for his money.
