It's important to note here that our understanding of Kennedy's disbelief in germ theory isn't based on speculation or deduction; it's based on Kennedy's own words. He wrote an entire section on it in his 2021 book vilifying Fauci, titled The Real Anthony Fauci. The section is titled "Miasma vs. Germ Theory," in the chapter "The White Man's Burden."

Don't you just love it when your insufferable boss comes to the photo op, insists on sitting at the lab bench, and pretends he helped? John Bardeen (left), Walter Brattain (right), and William Shockley (seated). These three men won the 1956 Nobel Prize in Physics for the invention of the transistor.

If a monkey hoarded more bananas than it could eat, while most of the other monkeys starved, scientists would study that monkey to figure out what the heck was wrong with it. When humans do it, we put them on the cover of Forbes.
