Query: someone not quoted in the book

I thought this book was the most horrible thing I've ever read. The lies, half-truths and hypocrisies should have this book listed under fiction. How bad is this book. When you have to have someone, that is a source for the material in the book, come online and give it a positive review it can't be worth a damn. That's right. David E. Barlow (who hides in the halls of academia) is quoted throughout this book and found it necessary to come here and defend this book by giving it a 5 star review. Those who can, do; those who can't, teach. And the truth never needs defending.
