To his fellow conservatives, John Derbyshire makes a plea: Don't be seduced by this nonsense about "the politics of hope." Skepticism, pessimism, and suspicion of happy talk are the true characteristics of an authentically conservative temperament. And from Hobbes and Burke through Lord Salisbury and Calvin Coolidge, up to Pat Buchanan and Mark Steyn in our own time, these beliefs have kept the human race from blindly chasing its utopian dreams right off a cliff.Recently, though, various comforting yet fundamentally idiotic notions of political correctness and wishful thinking have taken root beyond the "Kumbaya"-singing, we're-all-one crowd. These ideas have now infected conservatives, the very people who really should know better. The Republican Party has been derailed by legions of fools and poseurs wearing smiley-face masks.
