It doesn't matter what I 'feel'. It matters what I think. And I don't agree with you that a women's 'body' has secondary rights. My operating principle is that no one, the woman, her boyfriend, the participating doctor, has the right to deprive that fetus of it's right to live. Since that fetus is completely dependent on on it's mother to survive, that mother has the moral responsibility to provide for it until birth. I am 100% down with doing everything possible to help her raise that child with whatever social programs are necessary if she can't provide for that child after birth. Or, she could put that child up for adoption (thought the system is broken:

From a non-faith based perspective there is a moral and scientific framework that maximizes the woman’s bodily autonomy while still treating a fetus with value.
From first principles it’s do no harm to a person and respecting their rights to their own bodies.
From a scientific perspective a person must have something like a functioning mind to be a person that harm can be done to.
We do declare formerly alive people to be dead when they are brain dead even if their hearts are still beating. Ending life support is not considered harming them as there is no them to harm any longer.
Similarly until there is something like a functioning mind there is no “one” to harm if a fertilized egg fails to implant or a miscarriage happens before the brain starts functioning.
By 2X weeks fetuses start having REM sleep which seems to me to be a pretty definitive line of a functional brain.
The good news is by that point the risk of miscarriage is pretty low ~ 1/4000
So spontaneous abortion, elective abortions, and miscarriages before ~20 weeks doesn’t bother me because no one is yet being harmed and it’s the parent(s) right to decide if she (they) are bringing a baby into the world.
After that virtually all abortion are for medical reasons. If it’s to protect the mother almost all babies can be delivered after ~26 weeks and survive and abortions wouldn’t necessarily be required.
If it’s because of a defect incompatible with life then it is the parents right and responsibility to determine what the best course of action is for them and their child. You wouldn’t take away the rights of the parents to determine end of life care for their child dying of cancer would you? So why do that to the parents of the unborn.
