Children aren’t commodities, and families should not be seen as toy sets, uncompleted until you have all the different figurines. When someone spends £30,000 flying to New York to select the sex of their next child, they aren’t choosing life. They are choosing a lifestyle. And that is very different.
Actually, ever since we said as a society that whether to have a child or not, whether to take a pregnancy to term or to coathanger it, was entirely and absolutely only the potential mother’s decision, ever since then children have indeed been a commodity.
Once the pass has been sold then it is sold you see. Once the life or not decision depends upon what some other wants then there’s no reason at all why that want should not be determined by the desires over gender, eye colour, height, freckles or any other triviality. Societally we already agree that a club foot or hare lip is a sufficient reason for execution. Why not extend that to being ginger? Or male?
