People post pointers to massively comprehensive studies finding no connection between vaccines and autism. This is not so much missing the point as a failure of comprehension.

What the right wants is social approval—incessant, slathering approval—for torturing their children into normalcy. (Or, failing normalcy, for murdering them.) The objection to autism is not an objection to the brain chemistry; it's an objection to the idea that you don't have to make people normal by any and all means.
