Viability

Where you go from here will depend on their answer. If your conversation partner says no, then the main disagreement between the two of you is about the status of the preborn. It might be help to point out that viability varies depending on a lot of external factors that have nothing to do with the fetus herself. For example, in the United States we’re lucky to have great resources available, but in a developing nation with fewer and lower quality resources, the viability line is much later.

On the other hand, the person you’re speaking to might agree that the fetus is a valuable human person even before viability. In this case, the two of you mainly disagree about the ethics of killing. They might think that ending a pregnancy should always be an option, and until viability ending the pregnancy always also means ending the child’s life, but after viability that’s no longer the case. Ask more questions until you have a better understanding of their view. For example, clarify what they think should happen if a woman decides she wants to stop being pregnant after the fetus is viable.
