"Does the jovial bonhomie never end on this site?"
I don't know about LG, but I'm not particularly "unjovial" about all this. I mean, it would be nice if we could persuade you, and others, to be more open to mainstream Science and Medicine than is clearly the case at the moment. Equally, it seems unfortunate that of the two of us your views carry more weight, being as you are in a position of "power", to some extent.
In a lot of such matters it seems as if medicine suffers from its own uncertainty. Since, after all, the human body is far too complex a system to be fully understood, ever, that leaves room open for other ideas that can never fully be discounted -- like you said earlier yourself, no-one can prove a negative (not in the real World, anyway). But even while such ideas can't be ruled out completely, they can certainly be tested, and nearly always fail to pass the test, or never have been stringently tested in the first place. The two ideas discussed in this thread fail one of these tests: MMR causes autism (which is the main gripe I have with Wakefield's work; links between Autism and other diseases fall well outside my area of expertise) has been tested and no link has been observed; Antineoplaston treatment has failed what tests have been applied, and pretty badly, but hasn't been tested properly enough to rule out yet. The only person really in medicine who promotes the treatment is the inventor himself, but as he gets a lot of money out of it and has never released any Phase II or III trial results to the public, that's hardly surprising.
The world would benefit greatly from adopting the viewpoint that: (1) Mainstream Medicine (and Science in general) isn't always right, but (2) It is "right" -- or successful -- far more often than not, while (3) alternative therapies are far less trustworthy than conventional ones, because (4) there is an accepted standard of testing, and everything that has passed that standard becomes conventional.
