Smoothman, while I see that others have replied to you already I have not yet read them; they may contain similar info. Rest assured, the quackbuster Barrett and his AMA-sponsored quackbusting opinions do not merit or dignifiy concern or comment from any genuinie alternative health seeker and or provider. Strangley enough, of recent he has been literally thrown and laughed out of court multiple times in attempting to prosecute particular quackbusting; the odd aspect of this is that these same courts by and large are part of the same fraudulent establishment as the AMA, so either they have some subsequent twist to their agenda that has not yet been revealed, or they were having a slow day and experienced a temporary lapse of corruption that allowed them to truly judge his cases on their lack of merit.
In general, his basic methods for selecting targets seems to be based on attacking any of the many legitimate alternative practitioners out there. Linus Pauling is one who has become such a target, posthumously at that. Pauling was quite the scholar in various fields of Science and medicine; the primary alternative aspect to him was his research, knowledge and publication of knowledge on Vitamin C which ultimately was the reason behind the antagonism of the AMA towards him and subsequently it seems the attacks by Barrett. This alone should tell anyone all they need to know about Barrett. Not meaning to bend kneee to Pauling but if he genuinely deserves to be within the crosshairs of any legit quackbuster, the entire world of licensed medical practitioners and the AMA they rode in on deserve so as well. For the most part, even minus the Pauling factor, the entire world of licensed medical practitioners and the AMA deserve to be in the crosshairs of legit quack busters. )
