Reminds me of rule #4 from https://illimitablemen.com/archives/understanding-the-red-pill/game/

The western experiment of the Feminization of men, browbeating them into becoming crying and feeling and emotion-encouraging style women-males who use feminine tactics for survival in various institutions like family, education, military and politics has drastic unintended consequences very well expressed in Europe and to a smaller extent America. The birth rate has fallen so low (It's not enough to say "below replacement"). It's such a crisis in Europe that they have to import tens of millions of refugee migrants every year just sustain a modest 1% growth per year.

Someone has to bite the bullet and have (on average) 7 children. This means that some families have to have 10 to 15 each just to make up for the western male feminization expiriment. when you make women equal to men in every way. Political power, access to choice jobs, control over hard and soft assets, money and all the rest, why would have you have children, the birth rate falls to 1 which means every 20 years there are half as many people from the previous generation. Women to some extent need to be manipulated by physical force and domination to keep a civilization moving. Islamic State knows this well, it's outlined very clearly by Mohammad in the Quaran, keep your baby factories in chains, women are only worth one third that of a man.

A nation consisting only of females cannot defend itself against the onslaught of men, even if their land, sea and air superiority is an order of magnitude stronger.
