I found the following irresistable passage on Socialism in Jeff Greenfield's Slate piece on Obama:
One key to the movement's lack of popularity, Orwell argues, is its supporters. "As with the Christian religion," he writes, "the worst advertisement for Socialism is its adherents." Then he wheels out the heavy rhetorical artillery. The typical socialist, according to Orwell, "is either a youthful snob-Bolshevik who in five years time will quite probably have made a wealthy marriage and been converted to Roman Catholicism, or, still more typically, a prim little man with a white-collar job, usually a secret teetotaler, and often with vegetarian leanings … with a social position he has no intention of forfeiting. … One sometimes gets the impression that the mere words 'Socialism' and 'Communism' draw towards them with magnetic force every fruit-juice drinker, nudist,sandal-wearer, sex-maniac, Quaker, 'Nature Cure' quack, pacifist and feminist in England." (Think "organic food lover," "militant nonsmoker," and "environmentalist with a private jet" for a more contemporary list.)
Perhaps Andrew Sullivan should replace his blog's Orwell quote, "To see what is in front of one's nose needs a constant struggle." with some of the above. I suggest the portion I put in bold. Or perhaps I should replace my own introductory spiel with it.
