Earlier quoted context omitted.
On a personal level, children are optional; on a societal level they really aren't.
As crazy as it sounds, it still is a clear choice. It's a common trope in cartoons that the bad guys want the opposite - to destroy the world. I think you make an important point though, and I have no good argument to it. The best I can do is point out that having children does not fall on the responsibility of every woman. Not every woman needs to reproduce for society to continue. So the question is, is it okay for…
We are talking about the 2nd most powerful biological drive after survival. You wouldn't say "as crazy as this sounds, continued existence is a clear choice" - even though it is, because anyone could decide to kill themselves at any time. And therefore they're choosing not to at every moment they don't.
But you don't say that because that makes no sense.
And thus I say that the notion that having children, while yes in theory a choice, also reflects the second strongest drive after survival and is less of a choice than one might think.
