You don't have the pontificate authority to decide an unborn child is part of its mother's body.
It's not part of the mother's body, but no body has a right to another body. If it can't survive as its own body, that's just unfortunate. I view a fetus as a unique human body and fully support legal abortion.
If you can get a viable fetus out of a woman that doesn't want it, then by all means try to save it with medicine.
I'd like if more pro choice people fully said and acknowledged that. Maybe they do, but it doesn't seem like it to me. I just really dislike the flippancy of how abortion is described by some.
Like, the whole "it's just a clump of cells" talking point that used to be popular years ago is just so disingenuous ---
