Ok..wait a minute..I misread your post...you are correct in the sense of delivering early or removing Fallopian tubes. But that is not abortion. Abortion is the direct killing of an innocent pre-born human being. And the Church (as I have just shown) teaches that there are no circumstances where a Catholic can support provisions that allow for abortion (eg. rape, incest, medical reasons). Hench..no compromise.
The Church teaches that elective abortion is always wrong.
The Church does NOT teach that legislation, that seeks to protect life, and actually reduces abortions, is EVER wrong!
