or when they got to kill 1/4 of the citizens of a small country, or when they will enslave the 3rd world for its riches, or when they got one of the biggest countries in the world addicted to opium so they could more easily subjugate it (and how they do it to their own now), when they managed to depose a democratically elected communist making them enjoy unprecedented improvement just so they could turn it into one of the most brutal dictatorships in recent history for being afraid of what it represented, or when they helped elect a radical liberal and populist fascist so they could turn an entire country into a resource colony, or when they will quietly destroy the amazon rainforest while pretending to be the most progressive "leftists" on earth, or when they sanction innocent people and cause massive death and suffering because their prosperity would make capitalism look bad, or...
That "even if true" part undercuts the entire first part. Use a provable statistic and find a counter to it. Having a defined number for communism and nothing for fascism makes this feel like fascist propaganda to discredit communists. Capitalists will point to memes like this to show how dumb the community is when only the tin foil tankies actually subscribe to such poorly worded tripe.
I'd really like a source for the "200 million per decade" number, the closest I'm aware of is this catalog of US atrocities but that's both a wider and narrower subject than this one, not directly comparable.
