That vile nonsense has absolutely NOTHING to do with science or logic. NOTHING.
DM is a perversion.
Sigh. Its practitioners called it a science :-)
Foghorn Leghorn voice: "That's a joke, son. You're supposed to laugh."
And Haldane was a pest of the first order, an evolutionist AND a Marxist.
Kind of like, say, Pete Singer at Princeton is a "scientist" and trashes Christians. Or Dawkins. Or Sagan.
Many of the real scientists are Christians. But many of the popularizers (who end up defining "science" in the public eye) are definitely NOT.
