To be fair, RFK Jr believes that vaccines are linked to autism and wants to ban fluoride in drinking water because it's "linked to cancer". It's very worrying that he could be setting health policy.
I could have put it better, I think. But that's basically what I was driving at. Whether I'm off base calling him a 'weird crank', or have to behave as if he has more legitimacy (which will be difficult, though I could try harder), he's very much on record as wanting to ban and stop many things that in his mind are like terrible crimes against citizens.
I'm not uncomfortable lumping a lot of that together as 'medicine'. For instance, we know vaccination in general raises his ire, but he also seems to object to pasteurization. If he remains in a position to be able to ban that practice, it could be a significant driver of health-related issues. And I do think he's in a position to be able to ban or at least substantially punish the practice of pasteurization, vaccination, flouridation… it's unclear how much influence the man will have, but it could be a great deal.
