You know what else is unnatural? Hospitals, toilets, doctors, anti biotics, money, cars, videogames, iphones. Just because something is 'natural' does not mean it is good and and vice versa.
Depends on your definition of nature. There are problems with the mainstream definition of the term unnatural as anything man-made. But yes, just because something occurs in nature does not mean that it is 'good', or desirable. I have never claimed anything to the contrary.
We have outgrown evolution. We are so 'dominant' as a species that evolution no longer applies to us. People with maladaptive traits get a chance to live long enough to forward their genes.
That's hubris speaking and wrong. As I said before, selection is still at play, just selecting for other things. Whereas in the past i.e. Polynesian seafarers with an ektomorph metabolism were weeded out, the same happens now to people born sterile, extremely crippled, or wired to embrace 'the child-free life'.
Not wanting children is not genetic.
Prove it. We live in a deterministic, material universe. Our behaviour is to a large part biological/genetic, even when exposed to the same external stimuli people react differently depending on their nature. And even if you disregard that, these external stimuli in the form of societial pressure, are largely just the result of
collective genetic dispositions of past populations and their interactions with their environment. Aka another materially determined and ultimately gene driven process.
In short: A strong aversion to having children can definetely be what you would consider completely genetic no matter the upgringing. And even if your upbringing/society played a role, how you react to these external influences is as well genetically predetermined. Contraception will in the long rung select for people whose innate desire to have children is strong enough to do so despite it not being en vogue or economically advantageous as well as for people who are simply too careless to properly contracept.
The majority of people who undergo surgery to become sterile are probably already wired in a certain way, as it is not what the majority of people, even childless people would/did do such a drastic thing.
