I think it's reasonable to assume that people who did not have a bias against infertility did not leave as many progeny behind, so it makes biological sense.
The stigmatization of people who are infertile also destroy families which is counterproductive.
The idea however that it's always the woman's fault is just flat out wrong.
I agree with you on this.
Depends on what you mean by 'destroys families'. My argument was that this 'cultural instinct' exists because it creates families: the people who can't have a child will split up and find better child-bearing luck elsewhere. I knew a couple who was together for many years and they couldn't have a child. They split up (for reasons unrelated to children), and got new partners, and both of them immediately had children! Apparently some people are not compatible in that sense. Maybe someone could write an article about that!
I'm against stigmatization of course, but my argument is that, biologically, it can be beneficial, even if it's hurtful psychologically.
I get your point. Thanks for stopping by and please pardon my late response. I have been away for awhile.
