Responsible parenthood involves decades devoted to the child's proper nurture. To sentence a woman to bear a child against her will is an unspeakable violation of her rights: her right to liberty (to the functions of her body), her right to the pursuit of happiness, and, sometimes, her right to life itself, even as a serf. Such a sentence represents the sacrifice of the actual to the potential, of a real human being to a piece of protoplasm, which has no life in the human sense of the term. It is sheer perversion of language for people who demand this sacrifice to call themselves 'right-to-lifers.'
