I can't speak for anyone else, but:
(A) This thread does not bother me
(B) Saying the guy is naive is not vilification, condescending perhaps, but so much for political correctness
(C) It is at least as valid to bring logical and rational criticism of claims made in a public forum as it is to make those claims in the first place
Here's another criticism - individual evaluations of this sort will never have meaningful results. It is essentially impossible to control for all possible variables. It is the same effect that results in a market for $500 5-foot ethernet cables. If real science were actually involved instead of just hand-wavingly claimed, there would be results from testing akin to randomized control trials. If this stuff really worked as claimed the money that would come as a result of legitimate proof would easily justify the cost of such testing.
