But it could still be rape. I agree, which is why the Paul proposal is specious. A state barring abortion other than rape or life of the mother or even incret would face problems determining these things, not worth getting into here.
The Constitution imperatively requires the equal protection of the right to life of every person.
It was exceptions - ie the destruction of the fundamental principle of equal protection - that opened the door to abortion on demand.
And it is exceptions that keep abortion on demand going.
