I think you're missing the point. One's profession doesn't immediately disqualify their message. Nothing Hofstetter says in this video is untrue.
It's like saying you wouldn't cash a check written to your name for a million dollars just because you don't like the type of paper it's printed on. It's still a million dollars, and the facts he said are still true. The medium in which it's conveyed to you is trivial, and ultimately irrelevant, and the fact that you're so hung up on that particular aspect of it is a little odd.
