Something else which hasn't been mentioned yet.
Abortions will happen, regardless of whether they are legal or not. If women cannot access legal abortions, some will resort to dangerous, illegal procedures. This is historical fact.
Far greater net harm results when abortion is illegal than when it is legal.
It was vaguely mentioned back on page 3, but its always worth mentioning again. It's the point i agree with most, if a baby is not wanted people will become desperate to remove the foetus and if they dont have the safe means to do so they'll find their own ways of doing so.
