Sometimes revolutions are bad

Democide watcher Rudy Rummel disturbs (my square brackets): 

The total for the communist democide before and after Mao took over the mainland is thus 3,446,000 [Revolutionary wars] + 35,226,000 [miscellaneous] + 38,000,000 [knowingly induced famine] = 76,692,000, or to round off, 77,000,000 murdered...

This exceeds the 61,911,000 murdered by the Soviet Union 1917-1987, with Hitler far behind at 20,946,000 wiped out 1933-1945. 

For perspective on Mao’s most bloody rule, all wars 1900-1987 cost in combat dead 34,021,000 — including WWI and II, Vietnam, Korea, and the Mexican and Russian Revolutions. Mao alone murdered over twice as many as were killed in combat in all these wars.
