That’s a separate argument. I am not defending ABC. I am on the fence on that subject. I’m simply pointing out that your first argument is a bad one. I don’t think anyone here is saying that people should not have children at all. That would indeed be disingenuous coming from someone who claimed to love children. But there is nothing unloving about having one rather than two, or two rather than three, or three rather than four, or fifteen rather than sixteen, or twenty-four rather than twenty-five. . . . There isn’t even anything unloving (to children) about choosing not to have any at all oneself, as for instance celibates do. (Again, I’m not saying that it’s OK for married couples to choose not to have children.)
You can’t have infinite numbers of children. That does not mean that you “don’t love” all those potential children you don’t have. Or rather, not loving all those nonexistent beings is morally irrelevant.
