It's worth noting that at least 96% of money donated to Autism Speaks used for things like salaries and internal "research," and they have had exactly one actual autistic person on staff, who was there for a couple of years but publicly quit in protest after this PSA was released:
They also had some ties with the anti-vaccine movement for a while I've heard, although I haven't confirmed it.
They make PETA look credible by comparison (though to be fair, I don't think they've gone as far as saying that eating animal products causes autism, which PETA were saying for quite a while and may still be, although I think they recanted a couple months ago - hearing about that in passing last week is what led me to this, in fact), and they're pretty fertile ground for submission-worthy bullshit.
