CMV: The pro-choice movement hasn't done enough to justify taking rights away from a fetus

I was originally raised as a conservative christian in a very politically active household. This led me to be pro-life, among other things. I came to view abortion as the taking of a life.

Over time, I fell away from religion and became more and more liberal, but remained politically active. I personally am pro-choice but remain uncomfortable with abortion because I have never heard a pro-choice advocate reasonably defend the belief that the fetus has no rights compared to the woman.

I've seen the issue presented and argued countless times by both sides and it seems like there has always been a disconnect between them. Pro-life advocates argue on behalf of the rights of the fetus and pro-choice advocates argue for the mother's rights. 

The arguments that pro-choice advocates seem to hold to in this particular debate are scientific. Basically, it seems like if the fetus is not viable, then an abortion is okay. However, given how those in the pro-choice camp tend to be the ones who push for equality and core rights for other marginalized groups, relying on an argument such as science seems out of character. 

It's tough for me to really prove a negative (i.e. that they haven't addressed something) with a whole lot of detail and support, but this is a conversation I've really been hoping to have, and have tried to have with some of my good friends. I would absolutely love to have my view changed, as I am pro-choice (I don't see someone else's choice as any of my business) and I just have this one issue with that position. I would love to hear the philosophical, legal, or even a convincing scientific argument for why a fetus should have no rights until viability (or otherwise). Thanks :)

First up, under legal precedent going back a long way, a fetus is not a person. It has no rights. It is seen as part of the mother’s body. Long before the modern abortion debate this was often an issue in probate court, like when a man left his estate to his children and another was born after he died. Therefore, you can’t take away rights as they never existed. 

I feel that there’s an idea amongst certain pro-life groups that when an abortion happens, what is effectively an about-to-be-born baby is being killed. That’s simply untrue. Most abortions happen by about 9 weeks, when the fetus is under an inch long and very obviously not in any way a conscious human. Nobody is advocating for abortion at 9 months, and late term abortions are only allowed when there is a pressing medical reason, normally that the survival of the mother is highly unlikely if the pregnancy continues. That way the baby is not going to make it, either way.
