There is no denying this, and Gitlin, to his credit, does not try. Indeed, this self-imposed restriction and its malign consequences are the deep subject of the book. He provides an honest account of the reasons for his generation's disenchantment with patriotism—an account that helps explain why, even now, the term almost never escapes the lips even of mainstream liberal Democrats without being prefaced by the indignant words "impugning" and "my." For Gitlin's generation, the "generation for whom ‘the war' meant Vietnam and perhaps always will," it could be said that the "most powerful public emotion in our lives was rejecting patriotism." Patriotism became viewed as, at best, a pretext, and at worst, an abandonment of thought itself. It became of interest only in so far as it entered into calculations of political advantage. Far from being a sentiment that one might feel with genuine warmth and intelligent affection, it was merely a talisman, which, if used at all, served chiefly to neutralize its usefulness as a weapon in the hands of others, by making it into a strictly personal preference that others were forbidden to question: "my" patriotism.
why the left abandoned patriotism, and was it a mistake?
