If you believe the science in one arena, why not in another ?
I've had this same thought about the cdesign proponentsists. They spend a great deal of time denigrating both science and scientists, but when someone like Behe comes along with scientific credentials* and supports their cause, they rally behind the "science" he promulgates. They can't have it both ways.
* Note that I simply mean a scientific degree here and not necessarily scientific talent or ability
