I won't deny atrocities have been committed by communists, but let's not forget plenty of atrocities have been committed by capitalists too. Plenty of wars have also been fought by capitalist countries over material wealth. There has also been violence committed by proxy, the CIA alone has had its hand in numerous regime changes throughout the world, often favouring regimes that kept their people in line with violence.

I suppose the question then becomes what links the atrocities committed by communists and capitalists. Perhaps it's a power thing?

Let's look at what happened in Chile as one example, where you had Salvador Allende replaced by General Pinochet. Considering both of their records, do you think the CIA did the right thing in this case?
