Well, how can he make that determination when he's not even read the thing?
He's already determined what he's going to find when he reads it, if he even bothers to read it. Already a case of confirmation bias, and hardly impartial. So anything that Brock writes about this book is already disqualified from serious consideration, due to his confirmation bias, the bias with which he's starting with. It's not even close to being truthful, and you know it.
More the mystery that you continue to believe that he's a source of truth, when he's only a source of propaganda, as this instance clearly demonstrates.
