I never understood the "rare" part. Since abortion-lovers don't consider the baby alive, there is no reason to want to limit the procedure. A blob of cells is a blob of cells. We don't try to make cancer operations rare. We don't try to make dental surgeries rare. What's so special about abortions, if the tissue being removed is nothing special?
We don’t try to make dental surgeries rare.

I think that phrasing goes back to the early 1970’s timeframe when effective birth control was still an issue and pro-aborts were still concerned with gaining approval from the public. The “pill” was obscenely strong with serious side effects (plan “B” now is essentially just the early pill) , the IUD could only be inserted after a pregnancy , diaphrams were and are unwieldy and failure prone.. We indeed try to make dental surgery “rare” by offering effective preventive care.
