A Theory on Why Leftist Dogmas Change Every Week

It's a matter of changing the password, of course. If you set up an “Inner Ring” (as C. S. Lewis called it), you cannot take the risk of having people learn the password and infiltrate. In order to stop that, the password is changed every week, preferably to something that can be rapidly changed in turn.

Example: Is the Left for or against IQ tests this week? It looks like they've settled on testing nebulous characteristics that can be exchanged for even more nebulous characteristics at will. Is the Left for or against the War on Some Drugs? It looks like they're settled on only opposing “hard” (i.e., currently unfashionable) drugs.
