> the monomers for every single polymer in wide spread use show estrogenic activity
This is at least a bit silly. Ethylene is a gas, and it’s also a widespread, naturally occurring plant hormone. Propylene is also a gas. Lactic acid is a food and a widespread chemical produced by your body.
The article linked by the poster above was less about the monomers, which in many cases are not dangerous as you correctly say, but more about the junk additives that are included in almost any object made of plastic in order to decrease various processing costs.
The fact that the manufacturer declares that some object is made from a supposedly safe polymer like polyethylene or polypropylene is unfortunately not enough, because it may contain large amounts of non-declared additives and fillers that are much more dangerous than the base polymer or monomers.
Many plastics still are bisphenol chemistry based, just not bpa in particular. Turns out that that whole class of compounds is just bad news… but also essential for chemistry reason to make many useful plastics
