They believe you become a human when born, therefore to them the fetus is not human life.

That is not true at all. I don't know, and have never read about, anyone who believes that a fetus is not human until born. Most pro-choice advocates would agree that a fetus can be considered human when the cerebral cortex begins processing information like sounds and sensations outside the womb, which is around 5 months. That happens to fall in line with the 1992 Supreme Court case Planned Parenthood v. Casey, which set the upper limit for legal abortions in the US at 22 weeks, the point at which a fetus is viable outside the womb.

I would not listen to anyone who tries to argue that a 38-week-old fetus is not human. That's just nonsense.
