I participated in a discussion at the comment section of David Friedman's blog regarding the atrocities of Mao in China. Something to watch for in public discourse in the US is the kinds of atrocities that get discussed and the kind that don't. Everyone knows about the famines in China. Also the famines in the Ukraine under Stalin. Stalin and Mao are justly condemned for this. But death tolls that result from "friendly" institutions are usually less well known, even though the death tolls might be larger. This is some of what we discussed.
