L4L.org Libertarians for Life was founded in 1976 to show why abortion is a wrong under justice, not a right. Our reasoning is scientific and philosophical rather than pragmatic or religious. Politically, of course, our perspective is libertarian.
Human offspring are human beings, persons from fertilization.
There is never a right to kill an innocent person. Prenatally, we are all innocent persons. A prenatal child has the right to be in the mother's body. Parents have no right to evict their children from the crib or from the womb and let them die. Instead both parents, the father as well as the mother, owe them support and protection from harm.
