Once again you asking loaded, ignorant questions. The last time I just replied with another question of equal stupidity. This time I guess I'll try to give a better answer.
I'm saying the other 99% of the cases are not necessary for the mother's health. If we put the life of the unborn on equal footing in terms of rights of the mother, like, say we have two adult beings with completely equal rights. What you would propose is killing one of them because their existence is an inconvenience for the other. It's completely f**ked up.
