Thread by @StephenABoydPh1

At the suggestion of a really fantastic twitter friend, all-around awesome person and top-notch journalist, @JSweetLI , here’s a short thread of how utterly wrong @RobertKennedyJr is about science - like EVERYTHING he says is wrong: 1/n 🧵

The myth about fluoridated water has been repeatedly debunked scores of times. In water and all minerals, fluorine is an anion, meaning it’s negatively charged (“F¯”). In teeth (an “apatite” crystal), the F¯ migrates down along the crystallographic “c” direction, 2/n

“pulling” the calcium dications closer together. THIS is literally how it makes our teeth stronger and more resilient! Fluoride poisoning (“fluorosis”) only occurs in places like northeast Ghana, where natural fluorite mineral concentrations are high and,

due to acidic subsurface water sources, cause VERY high aqueous fluoride (>15mg/L) concentrations.

2.RFK Jr. is solely responsible for the sickening and death of scores of Samoans in 2018. He lied about the mistake made by nurses preparing the MMR vaccine

The myth of vaccines and autism has literally been debunked >100 times, yet RFK Jr continues to peddle the nonsense. Here: 6/n

factcheck.org/2023/08/sciche…

And I’m happy to explain the nonsense: dicationic mercury (Hg²⁺) is dangerous, yes. This is as a salt like Hg(II) nitrate, where it’s a freely floating in, say water. THIS is the very real source of Mad Hatter’s disease. 7/n

Haberdashers used to use this soluble salt to make animal skins and felt more pliable. Thimerosol is NOT that! Thimerosol is a covalently bound organomercury compound - chemistry matters! 8/n en.wikipedia.org/wiki/Thiomersal

Thimerosol works via the oligodynamic effect, where even a tiny bit (micromolar) of a metal-bearing molecule is toxic to bacteria.

There simply isn’t enough in the vaccine dosage to matter to humans!! Humans are bigger than bacteria! 9/nen.wikipedia.org/wiki/Oligodyna…

The human body literally doesn’t know what to do with any ethylmercury cation that may result, so we excrete it out in our urine! We even KNOW how long it hangs around - it’s called the half life because, you know, scientists MEASURE everything!! science = measurement. 10/n

RFK Jr. again lied about a connection between pesticides (specifically atrazine) and gender dysphoria. It’s mind blowing to me that people con so perversely twist around information to suit their own disinformational goals. 11/n nytimes.com/2023/07/06/us/…

What idi0ts like RFK Jr have done is they took a single study of farmers showing a slight drop in fertility, purportedly due to pesticide exposure, then made up all sorts of bullsh*t about it.

Here’s the actual CDC information on atrazine:12/n wwwn.cdc.gov/TSP/PHS/PHS.as…

Atrazine the molecule was discovered over 60 years ago and has a mind-numbingly high LD-50 toxicity ratio (TLDR: you’d have to EAT grams and grams of the powder to get sick or die). 13/n

The plain boring fact is that we simply aren’t exposed to it in anywhere near the concentrations needed to have any adverse effects on the human body 14/n. en.wikipedia.org/wiki/Atrazine

RFK Jr. lied again about there being a causative effect b/t antidepressants and mass shootings. This is YET another example of correlation NOT necessarily demonstrating causation! Politifact does a great job of teasing out the fact from the bullsh*t 15/n:
politifact.com/article/2019/a…

THIS is the guy we should be thanking! Maurice Hilleman was the number-one vaccinologist of the 20th century, having developed over 40 vaccines!! Where’s the biopic movie made of him??!!!

RFK Jr is a walking, talking ad for death 16/n = end
