Your “alternative” is nothing more that a ghoulish medical experiment reminiscent of Mengele.
I think you are the one with the problem with the obvious. The mother’s and childs rights are not equal here. The child had nothing to do with its conception, it is the innocent party.
The “mother” and I use that term loosely engaged in behaviour known to have consequences (pregnancy), failed to use widely available means to prevent the pregnancy, then says her right to be free of consequences trumps the childs right to life.
The mother is at fault and actions have consequences. She gave up her “right” not to be inconvenienced when she had unprotected sex. Therefore no right to an abortion. It is the childs rights that need to be protected
There is no alternative! It doesn't exist. And just how are you working for it? Are you a medical researcher working in a field of trying to transplant babies from one womb to the next? How is the research going?
pro-choice =pro-abortion
If you still want women to have a "choice", you still want them to be able to choose abortion.
