Abortion stops a beating heart. It is not right for a person to die because of the actions or whimms of its parents.

The baby can be put up for adoption. Not killed. We treat people on death row better. They have legal appeals to save their lives. Abortion involves an unborn person, that is what makes it different. The reason Margaret Sanger pushed abortion was to wipe out "undisireable" races.

The companion decision, Doe vs Bolton is the one that allows killing babies at any age, even while they are being born.
