And communists have murdered sixty million people over the ages - Antifa has no moral authority to judge anyone for anything.....
I believe the number is closer to 100 million. I think Mao alone killed 60 million. Stalin at least 20-30 Million. Khmer Rouge I think did about 2 million.
But yes, other than Islam, Communism has killed more people in history than any other ideology. (except Islam)
