PTFE is literally the first example mentioned in the Sample chemicals section of the wiki of PFAS, which you linked. Regardless of your views on whether Teflon is harmful, your comment contains misinformation. Teflon/PTFE is PFAS according to the OECD definition and the Wiki page.

Your point regarding whether all PFAS is harmful may very well be interesting but cannot be taken seriously if it is accompanied by blatant misinformation.

They list it as a "perfluroalkyl substance", which is exactly what I'm saying is wrong -- Teflon is nothing like the other substances, if only in that it isn't water soluble (it's more than that, but just for starters). You can't just group everything together under that category and claim they're all the same. These are ontological games played by people who either don't understand chemistry, want to scare people, are themselves irrationally scared, or have some other motivation for drawing the broadest possible definition of "PFAS".

If you don't understand the argument someone is making and have to rely on the verbatim language in a wikipedia article, you should probably resist the urge the label things "misinformation". Instead, just say "I don't like/agree with what you're saying", which is really what you mean.

My only point is that you use the term PFAS for a different group of compounds than multiple different official sources define it as. I'm just pointing out that that looks strange to me as a layperson.
