The facts are presented and linked in the article.
Major public health groups such as the American Dental Association, the American Academy of Pediatrics and the Centers for Disease Control and Prevention support water fluoridation, citing studies showing that the mineral helps fight cavities. Health groups also emphasize that the practice is safe.
Your scenario implies Trump lives to 98, and unless the preservatives in big macs are the key to longevity, I doubt he makes it that long.
I voted for Jill Stein in 2016 because I assumed Hillary was going to win anyway, and I was in a solidly red state so fuck it, might as well vote 3rd party.
Then Trump won.
Then I learned about Stein's backwards views on nuclear energy, GMOs and vaccines.
Then she turned out to be a Russian asset.
Then she decided to run again and again, knowing that she's only acting as a spoiler for the Dems.
Boy did I make a mistake in 2016. I wish there was a perfect candidate for everyone to vote for, but unfortunately keeping Trump out of the white house is the best we can do. Harris isn't my first choice, but I voted for her on behalf of all of the people who will suffer under another Trump presidency.
The article is drawing comparisons between what conservatives choose to be outraged by vs the things they actively engage in.
Her: No, silly. Protection for your penis.
My, crying: WHAT'S UP THERE??
If you only want to use or support open source apps, by all means do so. I tried Jeroba and Liftoff for a while, and while they had their merits, I am happy to pay a little money for the experience I get with Sync.
Again, if you just read the article it covers these points. It discusses that the CDC does not mandate fluoride and it's not ubiquitous. It talks about fluorosis, and the health benefits of fluoride.
I can of course take care of my own teeth, but that's anecdotal. If the data suggests that fluoride in water is a safe way to reduce the prevalence of dental issues, I'm for it.
