There should be a lot of natural experiments that can test this. Just find the boundaries of municipal water systems that fluoridate and take a look at the populations near the boundary but on opposite sides.
Often those boundaries will cut through a neighborhood and so you end up with a population of demographically similar households but some are on city water and some have wells.
Many of those neighborhoods will have fluoride levels in their well water that are quite different from the levels in their city water, making them good subjects for a study.
Give it up, don't use reason against conspiracy theories because they're exactly a refusal to think.
Evidence? Just look at the anti-vax paranoia after the Covid vaccine came along. Billions have been vaccinated, deaths decreased and idiots proudly say they won't take vaccines.

It is, that is the whole point of this discussion…
