We're rightly horrified by fascist murderers; why aren't we also horrified by communist killers?

Is There “something admirable” About Murdering People for the “greater good”? asks Matt Welch (hatip to Instapundit who answers tongue-in-cheek, "Yes, so long as you’re on the left").

… this Darragh McManus column, in Ireland's Independent, is a reminder of the opposite sort–that some people in the free world will continue providing intellectual cover for political mass murderers. Writing about Che Guevara, McManus ends his column like this:
