The newsletter I received had so many spelling errors, such as "Fluorinated" in this spot, that it was impossible to take seriously.

Citing RFK Jr. is equally spurious. Having a few (possibly) valid opinions within a nest of bizarre takes and often dangerous opinions does not make someone legitimate.

The fact that a nutcase for a president elect wants to elevate him also does not provide legitimacy. The fact that 78 million poorly informed voters voted for the nutcase, in turn, does not legitimize Trump.

The reason these voters are so poorly informed, in fact, is that they receive too much information from people who are not scientifically qualified to offer an opinion. It sounds like the author of this newsletter is no more scientifically qualified to write about Fluoride than I am. I don't write about this topic because I am not qualified to do so.
