Why was it painful?
Becuaee, oddly enough, I know Behe's 'real' research pretty well, on the physical chemistry of DNA. It's field in which I've also done some research. He wasn't a superstar (in case there's any doubt, nor am I), but he was a competent researcher. And Darwin's Black Box is so contrived, so tendentious, so easily refuted, it could only have been written by a true believer, or a charlatan. Either way, he traded in a good, albeit unspectacular, research career, and the respect of his peers, for the kudos of those who don't know any better.
