Does one really need references for this?
Aren't everyone aware of the massive socialist experimentations Mao executed on China's people?
The lowest estimate available is that 50 million people were killed (high end estimate closer to 80 million dead) due to political purges (cultural revolution etc.) and starvation (socialize farming, great leap forward, etc.).

> The failure of agricultural policies, the movement of farmers from agricultural to industrial work, and weather conditions led to millions of deaths from severe famine. Many also died from quota-based executions instituted by government officials. The economy, which had improved since the end of the civil war, was devastated.
See Mike Davis' Late Victorian Holocausts
So take these numbers with grain of salt and consider the book and its claim just a propaganda tool.

So your point is? Regardless of the actual figures, it was probably the worst genocide of History.
I find amusing that those so vocal against that period of Chinese history use the exact same methods to destroy critical discussion.
