Western ideas of liberty and agency came out of 1500 years of Christian. Christians put limits on liberty and agency, but that's very different than despising it.
Even from an atheistic standpoint, current levels of liberty and agency are clearly evolutionarily unfit. The fertility rate of Christians (and other conservative religious people) are at or above replacement level, which means that the unlimited liberty and agency folks are substantially below replacement levels.
This is something people don't seem to understand when it comes to pairing up and forming families. If there is no reliable method to do so and you leave it up to chance, then what's gonna happen? Of course, people will stop forming families at the rate they used to.
In a society where people only have enough children to replace themselves, having people without children means that society will slowly fade away and disappear.
There are a bunch of modern ideologies that don't try to understand or even deny that having children is the most powerful kind of democracy in life. When you are having children, you're essentially saying "I want more people like myself in this world". Under this premise, the western world is saying "I don't want to be here anymore".
Oh please, Christianity is no source of liberty. And as of now, conservative Christians are all about restricting liberty, that is literally their project. Conservative christianity despises liberty, but is all about forcing women into births and relationships they dont want and that harm them.
Even from an atheistic standpoint, current levels of liberty and agency are clearly evolutionarily unfit.
