Most people born now do still want to have kids. Even in my famously childless country (UK) 50% of women will have a child by the age of 30 (and a great many more afterwards.). Antinatalism remains a fringe belief.
What people do want is fewer children later. This actually makes the fertility crisis (which is very much more than a behavioural phenominon, you can jizz onto a microscope slide to get hard empirical data) a more significant issue. Since fertility decreases with age, changes that might’ve gone unnoticed when people had kids at 25 become catastrophic when people instead chose 35.
Perhaps you don’t want kids, that’s fine, I respect your choice. Most people actually still do! If this health effect is the result of (as some experts suspect) micro-plastic leached EDC’s (an environmental pollutant we have no suitable method of removing, which has a significant lag from production to release, and whose associated industry continues to expand) then saying “it’s no big issue we don’t need to worry about it” is (in essence) endorsing the forced sterilisation of many hundreds of millions, without their consent.
That is still a maybe, the evidence is far from conclusive, but do we really want another global-warming scale crisis on our hands just to dunk on Ben Shapiro?
