The specific evil in my mind was the Great Leap Forward, but there are dozens we could draw from history.

And I attribute them to communism because that's literally how history attributes them, though obviously pro-Communism thinkers would disagree.

This is important and rarely discussed. I'd add that there's a larger pattern tying these cases together, one that also speaks to some of the Encyclical's broader points: whether it's the Politburo of the USSR, the Court of Directors of the East India Company, or the Board of the United Fruit Company, historical atrocities in any age, society, or economic system almost always occur in the context of enormous power concentrated in few hands. It isn't capitalism or communism but the absence of accountability.

> What specific horrible evils do you mean?

The 1956 student massacres in Hungary, where my grandma was almost killed. The Holodomor, the various "Russianization" campaigns, the Jewish Autonomous Oblast, The Great Leap Forward, etc.
