Science's Pat Robertson
That's the pithy name given by John Derbyshire to "Darwin's Rottweiler", Richard Dawkins. Christians who cringe every time Robertson, ostensibly on their side, opens his mouth will perhaps feel empathy for scientists who read malarkey like this:
"The God of the Old Testament has got to be the most unpleasant character in all fiction: jealous, and proud of it, petty, vindictive, unjust, unforgiving, racist," he says. Dawkins then criticizes Abraham, compares Moses to Hitler and Saddam Hussein, and calls the New Testament "St Paul's nasty, sado-masochistic doctrine of atonement for original sin."
That sobriquet is just laugh-out-loud funny, and I hope it sticks.
