The Bible says repeatedly that murder is wrong. We can all agree on that. Believer or not, we can also agree that murder is wrong.
The Bible does not talk about the unborn. Even if you don't agree, that is a fact.
I am not in favor of abortion. However, I am not about to speak for God.
We cannot all agree about is whether the blastocyst / embryo / fetus in a woman's womb is a "baby".
However, babies are a good thing. Maybe we could agree that reducing the number of abortions would also be a good thing?
Without calling the other side murderers? That cannot be helpful.
