Here's a complete, devastating, and convincing takedown of the "CDC whistleblower" claim endlessly repeated by Natural News and its ilk. (Best line I've read concerning Natural News: "There's so much quackery it's like they're cloning ducks over there.")
David Gorski's blog Science-Based Medicine is the place to go for the real science involved in the hype about William Thompson, who was indeed part of CDC studies but has misinterpreted, slanted, and outright lied.
Along the way Gorski shows how idiotic the claims made by one RFK Jr. in this regard really are. Sadly, I don't think the son of a great American leader has ever produced anything on a scientific topic that was not refuted by real scientists.
