As to infanticide—you’d be surprised how many people on campus think an unborn baby isn’t human unless the mother sincerely believes he is. If the sincerity of her belief could make all that difference for unborn babies, why couldn’t it for born ones too? In fact, some pro-abortion people already think this way. Biochemist James Watson sincerely believes that babies should not be considered alive for three days after they’re born. Some people have sincerely suggested that three days are too few—they want thirty.
