I had the misfortune of eavesdropping on a conversation recently where some guy who was working in a bourgeoisie brewing facility recently switched jobs to work at a waste water treatment center and he was advocating for removing fluoride from water with a level of rationale that I have to assume he picked up from co-workers parroting information they heard on the Joe Rogan podcast.
Oof. I think we all have a moment like that at some point. Hope you can patch things up and express your frustrations to him in a more measured way.
