Even in the pages of the New York Times and The New Yorker, it seems the epithet 'virtuous,' when applied to an act of personal environmental responsibility, may be used only ironically. Tell me: How did it come to pass that virtue - a quality that for most history has generally been deemed, well, a virtue - become a mark of liberal hotheadedness? How peculiar, that doing the right thing by the environment - buying the hybrid, eating like a locavore - should now set you up for the Ed Bella Jr. treatment.
