I did enjoy his reading of his book. And I will admit that I found some of the ideas more compelling than I would have thought seeing them on paper. In particular, the religious overtones are somewhat offputting to me, on paper. Will see how I feel about them after a few day's reflection.
To the point of this post, however. If he his being pushed as a savior of some sort, I agree that is misguided. However, based on their merits, many of the arguments were compelling and I'm interested to see where they can be taken.
So, to that end, I'm not sure what the criticism "he's just cashing in" has to do offer here. What, exactly, are you accusing him of? Successfully presenting his arguments? Is that really such a bad thing?
Oddly, he just seems like an author, to me. If he is a figurehead, I missed that there was a movement. Is there more subtext to this? I assumed he just had a good seller. Oddly, many people can and do lay claim to that honor. It neither diminishes nor distinguishes it.
