If he'll pay me $100,000, I'll engage him in a debate. The money won't come to me, it will go to two or three charitable organizations. I'm not in it for money, I just want to get Dawkins to part with $100,000 of his money so that the money will not be available for mocking Christianity or other similar nonsense. Sounds pretty silly of me, no?
Well, swap in world-famous Christian apologist Ray Comfort for Mr. Dawkins and give Mr. Dawkins my spot, and you've got yourself the stranger-than-fiction true account of an atheist who is so afraid to debate that he's unwilling to accept $20,000 - twice his usual speaking fee of $10,000. (link)
