For example, one will virtually never hear that the Palmer Raids, Prohibition, or American eugenics were thoroughly progressive phenomena. These are sins America itself must atone for. Meanwhile, real or alleged “conservative” misdeeds — say McCarthyism — are always the exclusive fault of conservatives and a sign of the policies they would repeat if given power. The only culpable mistake that liberals make is failing to fight “hard enough” for their principles. Liberals are never responsible for historic misdeeds because they feel no compulsion to defend the inherent goodness of America. Conservatives, meanwhile, not only take the blame for events not of their own making that they often worked the most assiduously against, but find themselves defending liberal misdeeds in order to defend America herself. -- Jonah Goldberg
