On The American Spectator, Acton Research Director Samuel Gregg examines how the left wages “a war of rejection and rationalization against whatever contradicts their mythologies.” Which explains why leftists get into a snit when you point out factual details like how Communist regimes “imprisoned, tortured, starved, experimented upon, enslaved, and exterminated millions” throughout the 20th century. And it makes it so much harder to wear that Che Guevara t-shirt without being mocked in public. Gregg:

Overall, the left has been remarkably successful in distorting people’s knowledge of Communism’s track-record. Everyone today knows about the Nazis’ unspeakable crimes. Yet does anyone doubt that far fewer know much about the atrocities ordered by the likes of Lenin, Castro, Mao, and Pol Pot? Do those Occupy Wall Street protesters waving red hammer-and-sickle flags actually understand what such symbols mean for those who endured Communism?

But while the left’s response to such awkward queries won’t likely change, the unanswered question is why so many left-inclined politicians and intellectuals play these games.

Part of the answer is the very human reluctance of anyone to acknowledge the dark side of movements with which they have some empathy. Even today, for example, there are Latin Americans inclined to make excuses for the right-wing death-squads — the infamous Escuadrón de la Muerte — that wrought havoc in Central America throughout the 1970s and ’80s.

The sheer scale of denial among progressivists, however, suggests something else is going on. I think it owes much to the left’s claim to a monopoly of moral high-mindedness.
