I can understand (but disagree strongly) those arguing abortion should not be provided "on demand", but I completely fail to understand why a woman should be forced to give a birth after being raped or to basically commit suicide when abortion is required for health reasons. I wonder how can anyone defend this.
If you think an unborn fetus/embryo has reached the point that it should be considered human life and protected, then the tragic circumstances of how it came to be don't affect that. That said, while I don't favor rape/incest exceptions, I'm also not in favor of prohibiting all abortions. Roughly speaking, I think first trimester abortions should be allowed, third not allowed save to protect the physical life of the mother, and second I have no strong feelings on, but as I said, no rape or incest exceptions.
