@futurebird I'm not entirely sure, but grifting (selling "wellness" products), an unacknowledged belief in eugenics, the idea that public health is more about individual choices and responsibility than group efforts and responsibility to the whole, and an overdeveloped skepticism of existing science that partially derives from the former traits.
At least, that seems to explain a lot of his behavior to me. Basically, a wholly unqualified person for the authority and responsibilities he's been given.
I often think RFK is the most dangerous of the bunch.
