You are clearly stuck in the past, take a walk and open your eyes. It's the year 2020. Learned about communism in school, 20 million estimated dead, worse than the nazi's in fact.
20 million only covers the kulaks, and Stalins purges. It was certainly over 100 million. Mao is responsible for 70 million at the very minimum. Xi has a couple million on his hands. Plus all the covid numbers.
