I'm not going to argue the merits of anyone's evidence on this subject, but I don't think it is possible boil down the increase in Autism to any one particular agent. In all likeliehood, it is being caused by a mixture of different factors, such as genetic factors, environment, pre-natal disease in mothers, the increased use of psychoactive drugs in the last 30-40 years, and who knows what else.
If you really want to attack the validity of any particular study, you better have a degree in Bio-Statistics. I'm assuming the vast majority of the people posting about this don't, including myself. I do have a friend who has such a degree, and it a very complicated field, with a lot of nuances that lay people wouldn't understand. Also, a lot of people who do research studies don't necessarily have the training as Bio-statisticians, so they can come to false conclusions quite easily, albeit unconciously. My friend, who is very good in her field, has looked at studies and ripped them apart once she has actually looked at the raw data.
