People asked me to back up my assertion on Fox&Friends... The figure is actually 149,469,610 killed by communists, according to researcher, RJ Rummel, in his book "Death By Government". He likes the term "Democide." Socialism, folks, as much as they wish to redefine it, is just a path toward communism. That's why many of the communist nations call themselves socialist.
People's Republic of China
Body Count: 73,237,000
1949-Present (57+ years and counting)
R.J. Rummel originally estimated China's body count between between the years of 1949-1987 to be 35,236,000 (Rummel 1994). This excluded 38,000,000 million that died of famine during the Great Leap Forward. After the release of Mao: The Unknown Story, Rummel became convinced that the Chinese government was directly responsible for the famine, thus increasing his original estimate by 38,000,000 (Rummel 2005). 1,000 was added for Tienanmen Square in 1989 (Courtois 1999).
There's more information here.
Furthermore, those figures do not include the NAZI body count (20,946,000 Non-battle deaths):
The Nazi Body Count represents non-battle deaths caused by Nazi Germany between 1933 and 1945. This includes genocide, execution of civilians and POWs, forced labor that resulted in deaths, bombing of civilian populations, imposed famine and resulting diseases, and “euthanasia.” These numbers do not include civilians who got caught in the cross-fire of battle.
People try to argue that capitalism has killed more. Really? Where? Wouldn't that be just like the communists - to try to cover up the incredible atrocities of the capitalists against humanity! (NOT!) Just stop... just, stop it now. Capitalism coupled with the freedom we enjoy in this country has producing the greatest wealth and prosperity the world has ever known (also known as the middle class, which is suffering unduly under the socialist policies of this current administration). The success of capitalism is exactly why why they must try to tear it down at every turn. What's fascinating to me is that even with all the government murder and mayhem, people still love their freedom and their capitalism. It must drive the commies crazy!
