The famine stuff I could write off as honest mistakes by a misguided but well meaning leader. Mao's role in kicking off the Cultural Revolution as part of his internal power struggle with the CCP can hardly be excused the same way, it was profoundly evil. The CCP today can recognize some of the faults with Mao, and even acknowledge that the Cultural Revolution was a disaster, but shy away from acknowledging Mao's causal role in that.
“Thus, the Communist and Cultural Revolutions represent some of the most radical
attempts in human history to eliminate the advantages of the elite, and to eradicate inequality in wealth and formal education.”
