Perhaps you didn't see what post I was replying to, but it would help in order to understand the context. The OP said "there is virtually no developed country that allows abortion this late in the pregnancy" and this is a common misunderstanding about abortion law, particularly in the US. Almost every single person that learns there are a number of states that allow elective (i.e. non-medically necessary) abortion up to the moment of birth, are blown away and don't believe it. But it's true.

Most people believe that if the life of the mother is in danger at any point, abortion should be available. Not everyone, but the vast majority. Most people believe that there needs to be a cut off at some point (generally after viability, but this varies) where non-medically necessary abortions should not be legal. If you take a poll of 100 people, how many would support a non-medically necessary abortion at 8 months? Not many. So then the question is, why are there states with zero restrictions that late in term?

As to your claim that "nobody" would abort that late in term unless medically necessary, we know that is categorically false. Hundreds of already born children are murdered by their parents every single year in the US, so it's inexcusable to give them legal cover to do it prior to birth when the child is viable.

What is the difference between an elective abortion at 8 months and just smothering the baby after its born?
