When will it occur to good and decent pro-life people that the right of a woman to be secure in her person is violated by a rapist and the spawn that may be created by that involuntary act, and that the right of a person to be secure in her person from an unreasonable seizure is guaranteed by the Constitution? When talking about the right of an unborn person to life, we must take into account the rights of the mother to be free from having to tolerate the seizure of her person by another person. She must be allowed to end the seizure, if she wants to, but the baby must be allowed to live, if it can. Governmentally protectable life begins at the point of independence from the body of another soveriegn person.
The "spawn" of a rapist is an independent being with its own genetic signature. Western society long ago discarded the notion that the sin of the father passes to the child.
While your rights argument does have merit in the case of a pregnancy that threatens a mother's life, inconvenience cannot be considered grounds for murder.
