There's an element of paradox there - that at least you know where you stand with the fundamentalists. I mean, they're absolutely clear in their error and their stupidity, and so you can really go after them.

Time and again, my sociobiological colleagues have upbraided me as a turncoat, because I will not agree with them that the ultimate criterion for the success of a meme must be its contribution to Darwinian "fitness".
