What if I told you Pol Pot was the worst of the lot. When it comes to body count the people in this meme never reached half of their country's population(not for a lack of trying though). Pol Pot was the only one to get literally half of this country's population murdered.
But Pol Pot did communism wrong. We'll get it right this time. The bloody history of the 20th century and the 100,000+ lives lost were necessary sacrifices. Just one more chance is all we need.
Marxists tried their best to destroy the native cultures of these countries. They want everyone to look and think alike. National identity is the enemy of global communism.
