This is almost tragic: how the mans inherent un-trustworthiness poisons the air around this topic.
The reason some of his wacky stuff gets embraced to the degree it does (instead of immediately getting laughed out of the room like flat-earther stuff) is because the drug companies have made themselves untrustworthy to a certain degree as well.
We can't necessarily let the drug companies and healthcare establishment off the hook scot free for the role they've played over the last 25 years in making mainstream medicine seem less trustworthy in the eyes of a lot of people.
People tend to look at these things through a lens of "compared to what alternative?"
Unfortunately in this case, the "what" RFK gets compared to are the people who brought us:
"We see no evidence that Oxycontin is habit forming"
"Vioxx is completely safe, and concerns about risk of stroke are overblown"
J&J/Janssen in particular has had numerous scandals over the years... One recent case would be the near billion class action lawsuit they just had to shell out to people in the US & Canada after years of insisting that their talc based baby powder was safe. Apart from the fact that the talc by itself was found by the WHO and FDA to be possibly carcinogenic to humans when used in the genital area on females... they were shipping out batches (as recently as 2019) that were found to have asbestos in them, something they initially denied and publicly tried to attribute to FDA testing facilities making mistakes or being contaminated.
Compared to an honest, transparent, shining corporate stewards, RFK would seem like a complete loon for many of his ideas.
However, when compared to the entity that brought us the biggest addiction epidemic in modern history, "stroke in a bottle", and asbestos-laced powder for baby's nether regions... The raw milk/vitamin A/ivermectin stuff doesn't seem quite as wacky as it should in comparison.
