I didn't even use the most unambiguous Behe quote, where he says he accepts common descent as a given.
"he accepts common descent as a given."
Its common knowledge the Behe "accepts common descent" so that he is not fired, sent off to Siberia, etc. You types also will still listen to him. Besides, its illogical to argue that irreducible complexity refutes darwins theory and then accept common descent.
