Has there ever been a case where something like #2 has happened?
Don't think you need to worry about that one.

Personally, I give my kid water with the flouride filtered out via RO, but will still use topical flouride, e.g. toothpaste and treatments applied by a dentist.
I hate how issues like this are politicized... if I raise this issue anywhere, including on here I expect to be attacked for being a "conspiracy theorist" and "like an anti-vaxxer" etc. There is something really wrong when you aren't allowed to even talk about both sides of an issue- especially if, like in my case, I have a doctorate in the life sciences and am qualified to have my own informed scientific opinion based on the evidence.
How would you define "domain of expertise"? Reviewing literature from other fields I don't research myself and forming an opinion on how it applies to my research is part of my job and something I do almost every day. I am even also called upon to peer review articles and grant proposals that are not within my direct field of research, as is general practice to get "outside opinions."
In cases like this, I am able to be familiar with basically everything published on the issue. However an actual researcher in a specific field will have additional knowledge and opinions from firsthand experience, that cannot be found in literature.
In general, I think it is okay to have your own opinion on something even if you aren't e.g. a professional whose whole life is focused exactly on that one issue. No formal training, credentials, or firsthand experience are necessarily required to have an informed opinion. However, you still have the burden of making sure you really understand the issue deeply - which is probably something like 100x the effort most people think it would be. Anyone can do that if they take the time to do so. I wish more people would.
In any case, this was a few years back when I looked into it, and it seems like these concerns have become more mainstream and less controversial in the last few years, e.g. https://ntp.niehs.nih.gov/publications/monographs/mgraph08

Most notably (in the context of un-intuitiveness), is Xenon - it is't even a chemical, but an element - a noble one, which is almost nonsensical given most's flawed intuition.
> fluorine is not a noble gas
…what?
I haven’t the faintest clue what you’re talking about. I don’t think you know what the word “psychoactive” means, either. By your definition, water is psychoactive too. Is that what you’re suggesting?
