Folks, I hate to disabuse my good atheist friends of their beliefs–even if you are atheists–but the facts just do not support your mythology. The worst genocides of the 20th Century were not conducted in the name of religion or as a result thereof…but rather by your side, to wit:
Mao Ze-Dong (China, 1958-61 and 1966-69, Tibet 1949-50) 49-78,000,000
Jozef Stalin (USSR, 1932-39) 23,000,000 (the purges plus Ukraine’s famine)
Adolf Hitler (Germany, 1939-1945) 12,000,000 (concentration camps and civilians WWII)
Leopold II of Belgium (Congo, 1886-1908) 8,000,000
Hideki Tojo (Japan, 1941-44) 5,000,000 (civilians in WWII)
Pol Pot (Cambodia, 1975-79) 1,700,000
Kim Il Sung (North Korea, 1948-94) ) 1.6 million (purges and concentration camps)
Menghistu (Ethiopia, 1975-78) 1,500,000
Fidel Castro (Cuba, 1959-1999) 30,000
