What a surprise, the conman Darryl Issa supports this, and rather depressingly Dennis Kucinich jumps in with both feet:

I’m not exaggerating. The Committee on Oversight and Government Reform held a hearing trying to look into the cause and prevention of autism. Rep. Dan Burton (R-Ind.) launched into a several-minute diatribe (beginning at 12:58 in the video above) that starts off in an Orwellian statement: He claims he’s not antivax. Then he launches into a five-minute speech that promotes long-debunked and clearly incorrect antivax claims, targeting mercury for the most part. Burton has long been an advocate for quackery; for at least a decade he has used Congressional situations like this to promote antiscience.

In the latest hearing, Burton sounds like a crackpot conspiracy theorist, to be honest, saying he knows—better than thousands of scientists who have spent their careers investigating these topics—that thimerosal causes neurological disorders (including autism). He goes on for some time about mercury (as does Rep. Dennis Kucinich (D-Ohio) starting at 21:44 in the video), making it clear he doesn’t have a clue what he’s talking about. For example, very few vaccines still use mercury, and the ones that do use it in tiny amounts and in a form that does not accumulate in the body.

Talking about the danger of mercury in vaccines is like talking about the danger of having hydrogen—an explosive element!—in water. It’s nonsense.

I won’t go further into details, because this shameful travesty of truth and medical health goes on for an hour. On Forbes.com, Steven Salzberg wrote a fantastic article about this Congressional farce. I strongly urge you to read it, since Salzberg brings the hammer down on the Congresscritters who think they know more about science than the scientists who actually devote their lives to this topic.

Let’s be clear, the anti-vaxers do more than hurt themselves, and their hapless children. They harm those for whom vaccines have limited effectiveness, or who are too young, like Dana McCaffrey, because they destroy herd immunity.

The modern version of this was started Andrew Wakefield by a con man who had an interest in a (surprise, non working) “treatment” alternative ginned up a phony controversy to line his own pockets.

The people who support this crap are being either evil or stupid.
