At some point, we become inured to the shrill Chicken Littles who make a crisis out of everything they wish to control. It all makes The Englishman want to blow smoke in their faces.

George Will, in today's Our puritanical progressives, says it this way:
Progressivism is a faith-based program. The progressives' agenda for improving everyone else varies but invariably involves the cult of expertise - an unflagging faith in the application of science to social reform. Progressivism's itch to perfect people by perfecting the social environment can produce an interesting phenomenon - the Pecksniffian progressive.
I have no desire to be improved, unless they can make me taller, smarter, richer, and better-looking - and a few years younger. I would pay money for those things. She Who Must Be Obeyed would pay money to get those things for me, too.
