Or is it, perhaps, possible that, if there is indeed a real increase in the rate of autism, it's because of something that has nothing to do with our modern pharmaceuticals?
Could it perhaps be related to the increases in various kinds of air pollution? Water pollution? Pesticides or herbicides in our foods? Or even the dramatic increase in EM signals being broadcast everywhere?
Until there are reputable studies that can actually show something resembling a causal link, getting angry at the medical community, pharmaceutical manufacturers, or vaccine makes for saying they are not responsible is pointless and counterproductive. So far as everyone knows, it really wasn't them.
And while there may be some small subset of people "accusing suffering parents of being crazy", by and large that's also not something that's happening.
