I think "safe, legal, and rare" is something that should be true for abortions. But it's not my place to tell another woman that she HAS to sacrifice her body, something that she has taken care of and has to take care of her entire life, and grow another person in there.
I believe that supporting and educating women will definitely help lower the abortion rate. Allowing other people to make a situation-by-situation case isn't smart because total prolife-rs would draw it out until it's ruled that abortion is illegal, plus it's really not anyone else's business why as long as it's not a functioning human being.
As long as the fetus isn't able to survive outside the womb, I don't consider it an entire person.
