If you really want to talk about "burden of proof" and whether something "seems illogical", I'm going to take the easy way out and point out that PFAS is a set of substances which include PTFE ("teflon") as well as PFOA (used in the manufacture of PTFE). We have been conflating the two, which means many of the sources you provided for PFAS are actually invalid, at least in the context of discussing whether non-stick pans are "poisonous".
Technically the original discussion was about PTFE (ie. the stuff used on pans), not PFAS (which is what your sources reference since your first reply). If anything, you're the one who moved it my subtly moving the discussion to be about PFAS. I suppose it's "moving the goalposts" to bring the discussion back to PTFEs, so I do apologize if you think that me replying to your comments constitutes acceptance of moving the discussion to be about PFAS.
>don't provide any evidence again
Here's my "evidence"
https://en.wikipedia.org/wiki/Polytetrafluoroethylene#Safety
>PTFE is stable and nontoxic at lower temperatures
You have the burden of proof to prove your claim/belief. I already provided a source that says "80 percent of human exposure comes from consumer products in the home." which you're making the illogical leap that that must not include pans coated in these chemicals that we use to cook on... That seems illogical. Yes there are other sources of PFAs, but you're trying to exclude one of the most obvious sources.
>That's perfectly consistent with my prior claim that "finished non-stick pans are safe"
You have literally cited zero evidence for your claim--so no it's not consistent. You're pulling this out of your ass.
I strongly suggest you do a bit more reading on the subject: https://www.usatoday.com/story/news/2022/03/07/pfas-guide-ch...
Regardless, I'll keep using my cast iron, carbon steel, and enameled cast iron pans--you can keep eating weird chemicals.
