Foolish affectation of effete elitists and ivory tower Hampstead liberals. The ludicrous belief that the past atrocities of Democrats were morally wrong, and that future actions should be considered with precedent in mind. Often causes fascists to laugh in celebration.
Generally indulged in at Liberal Dinner Parties, where braying, champagne-swilling relativists indulge in self-righteous anti-Americanism while snorting fat lines of cocaine from photographs of Saddam Hussein, leaving Decent Observer columnists to seethe at their own frustrated impotence.
