To simplify the reasoning about this dynamic, I call it the duck lip effect.

At what point did "society" ask for duck lips? Where exactly did specifically men ask for it and actively select for it? If anything, they widely reject it. The expectation for duck lips does not exist, it was spontaneously fabricated by female influencers and that puts the idea and "expectation" in young girls' heads.

In other words, for as a long as we richly reward female influencers setting exactly the wrong example and being awful role models, this carries on.
