The Khmer Rouge
From 1975 to 1979, the Communist takeover of Cambodia by Pol Pot and the Khmer Rouge lead to horrific and destabilizing conditions. In an attempt to create a classless peasant society, Pol Pot systematically hunted and killed intellectuals, religious leaders, and city residents. Of the 8 million people in Cambodia, 1.5 million were killed.
I'm not sure where or how, izismile gets his facts... well, not facts really, leftist propaganda more like it. As in, Confederates raping "millions" of African-American women and, too, the items you mention as well as many others. Columbus a 'conquistador'... seriously.
Post entertainment, entertaining pictures, etc., not skewed takes on history in support of a Howard Zinn view of the world.
