I've been in academia and have been reading and writing on these subjects for many years, so I'm certainly prepared to read and learn from many conflicting opinions. I agree with you, there will never be a "final word", there's always room for further nuance and deeper knowledge. Sure, I am very firm in my opinion on this topic now, but were I to come across convincing evidence to the contrary, I would change my opinion. At present, I have read extensively on these subjects and feel comfortable with what I've written. I understand the subtleties, but disagree that they are as different as some claim. As always, I respect anyone's right to disagree, and welcome respectful intellectual debate.
