McCain: If I have to explain it, you wouldn't understand.

I'd have to dig out my old copies of Introduction to Objectivist Epistemology or maybe Philosophy, Who Needs It to verify this, but I'm pretty sure that argument would make Ayn Rand vomit.

It smacks of the "Everybody knows..." argument and the "It's a proven fact ..." argument. What shall we call it, the "If you question it, you don't understand" argument?
