Abortion
Ok this is absolutely bonkers this cursed debate even got that far in 21th century, but since it did, here's a statement.
Your life starts when you get physically independent from your parent. The moment your umbilical cord is chopped, you become a separate creature entitled to basic rights and protection. Before that, you are a part of a parent's body, at very best a parasite, and whatever they decide to do to you falls under criteria of body modification.
You don't have to justify removal of an annoying wart, or even a limb you've decided you don't need, to anyone.
