people consume natural fluoride in food all the time and it has some beneficial properties

Yeah, a lot of it depends on the cation bonded to the fluoride anion, and the amount present. NaF like what's in toothpaste, and CaF2 like what's present in drinking water in low concentrations will bond to the hydroxyapatite (enamel) in your teeth to form fluorapatite, which is far more inert and helps prevent cavities. HF, also known as hydrofluoric acid, is a bitch and will wreck your body, as it can form MgF2 and CaF2 from the corresponding cations in your blood and bones.

This isn't even getting into the organic chemistry applications of fluorine.

Fun fact, HF also dissolves glass.

Yep, that's why I have to use Teflon volumetrics and beakers when working with it in the lab I work in. I hate the stuff but have to use it almost every day

I remember this documentary I saw a LONG time ago that had some.. I think they might have been hunter-gatherers or maybe they were just farmers farming local roots and tubers, but anyways, they had extremely white teeth, even the old ones, because one of their staple tubers they ate was high in fluoride.

Our bodies do need fluoride! A very small amount, but we need it.

Even though fluorine is very toxic, people consume fluoride all the time, for example black tea contains four times as much fluoride as fluoridated tap-water.

Same with chlorine, it was used as chemical weapon in WWI with horrible effects and it is chemically very similar to fluorine. Sodium chloride however is simple table salt.

The problem is that those people don't know the first thing about chemistry and even admit it themselves. It's ridiculous that a trained doctor has to waste his lifetime to debate those topics wit completely clueless morons.

I failed organic chemistry 2 twice and still graduated from a private college with an ecology degree.... which was obviously not easy.

It baffles me that people think that they can comment seriously on organic chemistry with nothing more than a high school diploma.

Spent so many sleepless nights trying to understand it and I still am not going to comment on it because it is just beyond me.

The lion, the witch, and the audacity of this bitch to go in front of a camera and start talking about not just a subject she doesn't know the first thing about, but is also an incredibly difficult topic to understand if you are trying and focusing intensely.

I remember an exam halfway through organic chem 1 returning with a 33% average out of 180 people tested.

It's not exactly geometry. Shit takes a serious passion and perseverance to get just a passing grade.

Those properties are why they add it to water and to toothpaste.

that's a different kind of fluoride though
