The Pittsburgh Post-Gazette has an article by James Terence Fisher: RFK Jr., autism and long-debunked theories. If I start quoting, I’ll copy the whole article. So, I’ll just recommend you follow the link and read the article in place.
Prof. Fisher mentions “Autism families of a certain vintage”. I am of that vintage. I’ve watched his son grow up through blog posts over the years. I too saw Robert Kennedy over decades and David Geier promote bad science and bad medicine. The harm they have caused is real and it can only get worse with them in positions of power. Prof. Fisher gives another perspective on the history, from an autism father’s point of view.

Thank you. I followed his wife’s blog for many years, and still pop in once in a while.
(I know I should not read the comments, because they really expose the people you really want to avoid)
