nothing to do with RFK I was just piggybacking on the other comment mentioning him to further paint the original picture: history repeating itself, future culture trying to understand past culture by limited speculation, and future culture (being the present culture) that will eventually be the past culture and every present culture tends to think they understand things better than they actually do, so it’s fun to think of us talking about Rome and lead in water, and future culture talking about us and Fluoride in water, regardless of how accurate any of it is or related to “empire collapse”, funny to imagine there was someone back then saying claims about lead being possibly harmful are biased, whatever the personal motive was (ie, not wanting to believe they let their kids drink dangerous lead pipe water so they go out of their way to tell others that claims of lead being suspected to be dangerous are biased, which is itself a bias)
