Civil rights activists refuted racism in four words: "I am a man!" Because people of African descent are man (human), they ought to be treated as such. They are the kind of being who bears intrinsic value and inalienable rights, the kind of being against whom we may not discriminate on the basis of superficial characteristics such as race or skin color.
Children in the womb cannot speak for themselves, but the same question determines how we ought to treat them. Are they not man (human)? Human beings may not be killed for the reasons for which elective abortions are performed. Human beings may not be discriminated against on the basis of superficial characteristics such as age or stage of biological development.
Are they not man? Who will speak on their behalf?
