"Gentlemen, I do not mind being contradicted, and I am unperturbed when I am attacked, but I confess I have slight misgivings when I hear myself being explained." -- Lord Balfour, to the English Parliament

C S Lewis termed this "Bulverism", this device of explaining why X is so {dumb, crazy, misinformed, w/e} as to claim Y, without lowering oneself to arguing against Y. Lewis however was not above committing Bulverism himself.
