Well, we disagree.
A modern woman is someone born maybe from the 1960s to the 2000s.
The plurality of them are married, to a man, with kids. So I don’t think saying that most modern women want to abuse men’s hearts and wallet and then discover themselves alone and ruined at 60 is true. Many who are not married (like a daughter of mine) are still of the right mindset. Many who are divorced (like friends of mine) are divorced due to infidelity on the husband’s part. Not majority harlots.
There is a good sized subset that behave as you describe. It is post modern philosophy to do so. But the majority of women aren’t actually on the screeching feminist trail.
Your flaw is “modern woman” doesn’t mean “screeching feminist”.
But I’m done talking about it.
