You mean ten's of MILLIONS of people were KILLED!!
Very good - it was an OCEAN of blood, and it destroyed the essential humanity of the Chinese people. I know that's an extreme statement, but it's true. No Chinese person alive doesn't have some damage from that psychotic butchery - none. So many Chinese were murdered that it affected the resultant Chinese GENOME - real evolution in action. The only ones who survived to pass on their Chinese genes, COMPLIED with the communist horror, by definition. So generally speaking, genetically and psychologically, the Chinese people have been "purified" of their natural desire for human freedom - just as Mao planned - for it's no accident.
