Have you heard the latest conspiracy theory that sinister researchers funded by MIT, the U. S. government, and the Quaker Oats Company are giving radioactive breakfast cereal to retarded children without telling their parents about the nature of the experiment?
Oops, my bad. It's a historical fact, not a conspiracy theory--just one of many U. S. nonconsensual experiments from the 1930's-1960's. https://bioethicsarchive.georgetown.edu/achre/final/chap7_5.html
Sure, the QAnon story is nonsense and dangerous. But the real harm of the Nazis was not a result of their "new age" tendencies. In addition to their conquest for world domination and genocide (e.g. the Final Solution), they conducted experiments on helpless individuals (e.g. hypothermia research--which is chronicled in a meticulously clinical, dispassionately scientific format), as did the U. S. government. And after WWII, we imported some Nazi researchers through Project Paperclip. None of this is a secret nowadays.
While I don't agree with the anti-vaxxers, or the current anti-science ethos, I think it's equally dangerous to dismiss all questioning of so-called scientific research as new age / Nazi flummery.
