1. Should we check the menses to see if a life has been lost?
2. The zygote not implanting is no less a tragic loss than an unfertilized ovum passing. I’m not speaking about persons trying to become pregnant and struggling. But the zygote is at such an early stage of development, assuming a full term pregnancy is not desired, the termination of that development isn’t tragic. This is very distinct from a fetus much later long in development because then we’re talking about a fully fledged human being.
3. Why the qualifier? It shouldn’t matter at all the circumstances.
4. The opposition to abortion is chiefly on punishing women for having elective sex. If it’s really about “this human being will die without their womb” then why can’t the State force you to give up a kidney to someone who will die without one? All life is sacred, yes? The pro-life crowd must agree that the State has a duty to compel you to give up part of your body to preserve a life.
If you’re going to counter, “I didn’t choose to create you,” why does that matter at all? Unless the anti-abortion reasoning is about punishing women and not preserving life.
