> The relationship and obligations that a mother has to her child are fundamentally different to the relationship and obligations I have to a random stranger in the ER

You define "child" based on a religious definition. That's /your/ religion, not mine. Feel free to follow it all you want, you don't need to involve the rest of us. We're not talking about children, we're talking about fetuses.

> Do you really want to be play that game? Because I'll have a field day with you.

Ah, an internet tough guy. Feel free to "have a field day." Your entire argument is premised on the idea that a fetus is a human life, which only has basis in religion.
