It is worth noting that two very common tactics of avoiding this conclusion fail. The first is to defend abortion, on the basis of the perceived positive social consequences of ‘liberal’ abortion laws. In popular political discourse, and in some feminist writings, abortion is defended on consequentialist grounds; it is argued that abortion prevents unwanted children, children who are likely to be poor, abused, neglected or engage in crime. It is hailed as a solution to over-population and the existence of handicapped people. It prevents adult and teenage women from falling into economic hardship and stress and enables them to complete their education, pursue their careers and so on...
In summation, liberal proponents of the non-initiation of force principle can only support abortion if they are willing to be inconsistent and arbitrary in their application of the principle or if they are willing to endorse not just infanticide but the eating of newborn infants or state mandated vegetarianism or coercive abortions. These policies are an anathema to most liberals; as such, abortion is not liberal.
