After reading "Abortion vs. Adoption" I realized what it must have felt like to be an abolitionist in the 1850s.
In 1857 in the Dred Scott Decision, our learned Supreme Court declared that blacks were not legal "persons" and were the "property" of the slave owner who could do with them as he pleased, including kill them. In 1973, seven aging men on the Supreme Court declared that the unborn were not legal persons and that a mother could do with them as she chooses.
Although it took centuries, Americans eventually came to realize that slavery could never, ever be justified by any arguments. And someday we will come to realize that killing (and experimenting on) unborn babies can never, ever be justified to solve social problems.
