The Mao statue is no longer there. It was part of a temporary exhibit at the time, outside the museum. Inside was the Mao exhibit.
And Stalin wasn't far behind. His policy of forced collectivization of farms in the Ukraine and other parts of the Soviet Union between 1928 and 1934 may have killed over 15 million people from a deliberate famine.
And you wonder why the Left admires that very unusual monument--0he Georgia Guidestones. Especially chilling is #1 of ten inscriptions:
Maintain humanity under 500,000,000 in perpetual balance with nature.
Small wonder why the Left doesn't respect human life right now.
