The chemical differences between PFAS and vitamin A and B6 are beyond vast.

Comparing them betrays a complete ignorance of the molecular properties that, in combination with biological system processes, make A and B6 healthy at small doses and poisonous at large doses on one hand, and those that makes PFAS linearly poisonous at any given doses on the other. (And yes, you can be exposed to small amounts of toxins and be fine. That doesn’t change the toxicity of a given substance.)

Struggling to see how this could be anything but a bad faith argument.

It really feels along the lines of "prove lead is actually harmful rather than potentially harmful" with all the knowledge and evidence we currently have.
