Well, your 100% logical mind seems to have again discerned my/our intentions, my/our statements to the contrary. Way to analyze the data!
Those of us actually interested in determining the cause and the solution can take comfort in the fact that it will benefit even the skeptics and their families.
Did I say those were your intentions? Again NO, you really excel at reading stuff that isn't there. I clearly said "they" which is not necessarily "you" unless you've decided you're part of they; and you can't deny there is a section of the people trying to link autism and vaccines that are just plain anti-vaccine. There's a crowd of luddites in this world that likes to attach themselves to these kind of emotionally charged issues, and they're all pigs because they play with the emotions of people put in unfortunate circumstances to get backing and cover.
So far the only cause that's pointed to at all by the data is genetics. A lot of people don't like that answer because they think it reflects on them in some way, it doesn't, we don't get to pick our genes or how they'll divide and combine with our spouses genes. But some folks blame themselves anyway, and the only way for them to stop is finding some external cause no matter how tenuous the evidence.
