In no other situation is opting out of supplying blood, organs, etc to another person considered murder. It’s hard to imagine any government that required you even to give blood as anything but the extreme end of tyrannical, authoritarian, and monstrous. And, yet, this is the reality that women are subjected to.
We don’t even force dead people to give up their organs. Literally, dead people are considered to have a greater right to their bodies than pregnant women. Abortion is subjected to a wildly inconsistent legal standard.
