There's a kind of activism that's more about bolstering identity than achieving results, one that sometimes seems to make the left the true heirs of the Puritans. Puritanical in that the point becomes the demonstration of one's own virtue rather than the realization of results. And puritanical because the somber pleasure of condemning things is the most enduring part of that legacy, along with the sense of personal superiority that comes from pleasure denied. The bleakness of the world is required as contrasting backdrop to the drama of their rising above.
