Is it not true that a woman may deny another human use of her body? I’m not saying the fetus is her body, or that it’s acceptable to dismember him/her to remove him/her from the uterus. Also note I’m agnostic.
Hi! I have heard before the argument that a woman has a right to abortion on the basis of some form of “self-defense”, like you say, the baby is using her body, but it needs her permission to do so, otherwise it is assault.
Yes, any person has a legitimate right to self defense, though they do not have a right to excessive force. St. Thomas Aquinas says:
“If a man in self-defense uses more than necessary violence, it will be unlawful: whereas if he repels force with moderation, his defense will be lawful.”
And further, the Catechism says :
Therefore it is legitimate to insist on respect for one’s own right to life. Someone who defends his life is not guilty of murder even if he is forced to deal his aggressor a lethal blow: (2196)
It is possible that a moderate use of force will result in the death of the attacker, and that would not be unlawful.
But to intentionally kill a baby who is not trying to kill you? There is no right to intentionally kill him/her. Even if s/he is a product of rape.
Now I realize that opens up the case of abortion to save the life of the mother, but there are plenty of threads and websites that can answer that for you
You mention that you are agnostic. I am Catholic, nice to meet you!
