The only evidence that vaccines cause autism is one study [wikipedia.org] done in 1998 that was so horribly flawed that not only did The Lancet issue a full retraction in 2010, the doctor who led the group that authored the paper lost his medical license. ... the paper itself never claimed a link between autism and the MMR vaccine, yet that's how the media/idiots took it.
Interesting - you seem to be saying that the doctor lost his medical license (a pretty egregious penalty for a flawed study) because the media misinterpreted it. That seems pretty odd, but I don't really know the story, and far be it from me to be thrown in with the lizard people like you have done to the GP.
But you never addressed his basis, which is that every possibility from vaccines to food supplies to public policies and clearly old or flawed science being used to promote nutritional advice are being dismissed out-of-hand as simply not possible. That perhaps the drug-company paid-for FDA and the Monsanto-controlled Department of Agriculture really are not going to allow anyone to shed any suspicion upon the corporations that they work for, and an anomalous rise in autism has nothing to do with the lifestyle they promote.
We know that the standard bureaucratic processes often fail the public from stories like Lorenzo's oil, the Dallas Buyer's Club, and we are just starting to recognize that the people warning about wheat gluten may not be crackpots after all.
