You mean the French and Russians didn’t have slavery before their revolutions. But the Bolsheviks killed millions. And they established slave labor camps for decades.

And in the French revolution, just a handful of people caused thousands of executions.

[This led to the enactment of the Law of Suspects, which allowed for the arrests of between 300,000 and half a million citizens nationwide. 16,594 of these ‘suspects’ were formally executed after a trial, while around 10,000 died in prison, and thousands more were killed in various massacres staged across France. It is estimated that the total death toll during the ten-month Reign of Terror rests anywhere between 30-50,000.]

Did you really think I couldn’t back up my statement with facts? How is the Reign of Terror in France and the mass genocide in the USSR in any way “equivalent” to the American and Haitian revolutions?
