You're saying it's de facto selfish to not have kids? What if someone can't have kids?

In reality everyone who's thinking about having kids exists on a spectrum of what's possible: either it's going to be really easy for you (because you're Elon Musk and you don't give a fuck) or it's going to be borderline impossible (because you're infertile, or you're broke, or whatever).

Just because someone looked at the odds and said "you know what, maybe this isn't a great idea" doesn't make them selfish. Meanwhile you're the one imposing your worldview on them...

Productive conversation is infeasible with someone who interprets my position to be that it’s selfish to be unable to have children.

Not to put words in their mouth, but I think part of the poster's point is that inability is is a more complex equation than simple biological capacity. A couple who judges it economically risky or otherwise irresponsible to start a family (which represents a wide swath of the population) could for example consider themselves unable.
