I believe it's the culture that is making woman more liberal and not growing up around babies

In the UK in the 1990s there was an issue of growing teenage pregnancy and the UK government

So the government has young teens spend time working at daycare with babies but it had the opposite effect

It turns out young women actually like spending time with babies and it triggered their biological mothering instincts

To have babies

We live in an increasing anti child and anti baby culture

Also social media algorithms feeds men and women the content they naturally gravitate towards and which is leading

To a greater divide of political differences because both men and women are having different information given to them

Can spend years being fed information but by the time you get information from the other side your view is are already set

Also I would say most modern Man are liberals and women are having more socialist and redistribution tendencies
