I wouldn't question his intelligence but I'm not so sure about his heart.I read both his books, so I already do.
His heart is in the right place, however, so I appreciate that.
He may be just in it for the publicity. Or maybe even his unanswered question on Christianity. Highly intelligent people can't just let the questions go and not be reconciled.
He can reconcile nonsense such as Noah's ark or the 6000 year old earth but he can't do anything with the question on his belief in a god.
Without doing that he can never win another debate with an opponent who knows his bugaboo issue.
