Did you read the bio here?
This is my last reply, William Terrell, because I'm starting to think that you're being deliberately obtuse here.
I'm not judging his knowledge in one area by his knowledge in another-- I've judged his INTEGRITY, which is indivisible and essential, and found it wanting. Therefore, I have no interest in listening to the guy, on ANY subject, but most especially on a subject in which I am not an expert. (I COULD listen to him, without risk to myself, on a subject in which I am an expert, but 1) that's not the case here and 2) there's no reason to.) So, his credentials are of no interest to me, period.
Look at it like this-- would I take on a business partner whom I knew to be unfaithful to his wife? No. If he'll cheat her, the odds are much greater that he will cheat me. It's not assured, but why run the risk? There are plenty of other potential business partners of good character to deal with-- I don't need that guy.
