In fact the definition of "person" is not deemed absolute. The Fetus is a human being. A very immature one, but a human being nevertheless. Killing a human being is murder. Some of the criteria for defining a person according to some is not met by those in coma, those unconscious and some of those mentally ill. Relying on others to maintain life, for example. Consciousness and the ability to reason as another. When people have been lied to, and they have an abortion thinking it is just a blob of cells, I do not feel they should be held accountable. They have been told by countless authority that is was not a human being and not valued as worthy of preserving.. And, legally it is not murder at this time. So, only those doing the lying and those medical professionals who know better is guilty of actual murder in my eyes. The laws will change as people grow more aware. We have much better technology now than we used to. We can scan a fetus in 3D and see it's magnificent formation into a very tiny human being in mere weeks complete with a beating heart. Too bad the fetus can not talk. He would say, "A person is a person no matter how small". Abortion is also genocide of the poor and minorities who are more likely to abort. When there are countless methods to prevent unwanted pregnancies and there are countless numbers of loving homes available to adopt, to hold on to "My body, My Choice" appears very selfish!
