As others have said, its human nature - people will keep getting pregnant knowing they don't have the money or interest in raising a child.
Abortions are unpleasant but its just impractical, and in the end petty to make them illegal. All women will do now is cross the border to get it done.
Its a weird debate because in some ways its almost progressive to want equal rights for an unborn, unconscious fetus. At the same time I don't see a lot of the pro life people showing up to protest wars, or against police brutality.
They never do. Pro-lifers are complete hypocrites. Just look at how they treat the life when it's actually born. :/
