EXCERPT:
* Genghis Khan is said to have once killed 1,748,000 people in a single hour. But at least he did not eat animals.
Genghis did not only kill people...due to his prolific raping and procreational activities, his genes are the most widely spread in the world. Zerjal et al [2003][27] identified a Y-chromosomal lineage present in about 8% of the men in a large region of Asia (about 0.5% of the men in the world).
* Pol Pot - a vegan - murdered some 2 million Cambodians in his lifetime.
Pol Pot wasn’t just a killer. He also had organized an independent revenue source for the party in the form of rubber plantations in eastern Cambodia using forced slave labor.
His Khmer Rouge captured Phnom Penh on April 17, 1975. A new government was formed and the name of the country was changed to Democratic Kampuchea. Phnom Penh was full of refugees from the war. The new government drove all the refugees into the countryside without regard to the human consequences of their actions. Pol Pot also drew up death lists of former government officials who were to be executed on sight.
Out of a population of approximately 8 million, Pol Pot’s regime exterminated one quarter, or almost 2 million people.
Hundreds of thousands of people were taken out in shackles to dig their own mass graves. Then the Khmer Rouge soldiers beat them to death with iron bars and hoes or buried them alive. A Khmer Rouge extermination prison directive ordered, “Bullets are not to be wasted.” These mass graves are often referred to as The Killing Fields.
* Charles Manson - Vegan Animal Rights Activist
Manson: “I did it for ATWA! Air, Trees, Water, Animals!”
Charles Milles Manson (born 1934-NOV-11) is a person with an unusual ability to dominate others. He assembled a destructive, doomsday cult around himself, which the media later called The Family. At one time, it numbered in excess of 100 individuals at the Spahn Ranch some 30 miles northwest of Los Angeles CA.
Manson was an environmentalist and animal rights activist concerned about damage to the environment and pollution. He once commented: “Your water’s dying. Your life’s in that cup. Your trees are dying. Your wildlife’s locked up in zoos. You’re in the zoo, Man. How do you feel about it?”
The Manson “Family” later perpetrated a series of murders which shocked and terrified the nation
