I've enjoyed some of his podcasts, he interviews some interesting people, but like some other podcasters I sometimes wince when he's the one speaking.

It's entirely possible to have beliefs that are just wrong, and then monetize those beliefs, I don't think that's necessarily wrong in a moral sense. I get mad when I see homeopathic 'medication' in the pharmacy, they should know better, I get madder when I see 'does not cause drowsiness' on the side of the package, because that makes me think that maybe the people making the product know better too. I think they should legally have to put on the package that there's no reason to think the stuff does anything, let alone make you drowsy.
