Well, "the worse, the better" has been argued before. Nader suggested at one point that if Bush were to be elected, it would galvanize the American public against the Republican Party. And, not to say that it's worth the damage Bush has done to our country and to the world, but that certainly seems to be the case right now.
Of course, the reason Nader was right and the white supremacists are wrong is that they're making the same argument from opposite perspectives; he is suggesting that most people want civilization to move forward, whereas they are suggesting that most people actually want it to move backward and just don't realize it but will as soon as their reptile brains are stimulated by the horrifying image of a black man in the White House.
I sometimes wonder what it must be like to have a mind that works like that. But I try not to think about it. Whereas they simply try not to think about anything, at all, ever.
