Larry King had noted medical expert/softcore video star Jenny McCarthy on the program last night to talk about AUTISM. Specifically, how it's caused by VACCINATING YOUR CHILDREN. This is patent conspiratorial nonsense, but it's very popular conspiratorial nonsense. Of course, in a battle between concerned, credulous parents and medical experts, the media will generally frame it as, say, Debate Rages Anew on Vaccine-Autism Link. Faced with a panel of three trained pediatricians, Ms. McCarthy shouted "BULLSHIT" twice. Then Larry put it to an internet poll. Clip after the jump!
