Biologically it is human. A human egg and sperm fuse to make a human embryo. Personally, I think humans should be given human rights due to individual freedom. Why should blacks be treated as humans? What about whites, Asians, Hispanics, etc? I believe that a human rights is a right given to someone because we as a species value freedom and have a sense of morality. We don't deny minorities rights or others rights because we recognize that doing so is wrong and clashes with our sense of morality and freedom. As it is now, if anything to be consistent with the laws regarding human rights and equality I know that it's a violation to deny a fetus all rights and place its right to life below the personal feelings of a pregnant woman.As far as why it is unclear: What is a human, exactly? Why do humans deserve human rights? Do all humans universally deserve human rights? What is a human right?
I don't really think it leads to conflicts or contradictions. From the debates I've had I think the conflicts and contradictions exist in denying fetuses human rights and allowing women to electively chose whether or not someone else lives or dies. It's known fact that the embryo/fetus is all stages is human life, so the concept of "personhood" and the use of "personhood" to define if someone should have any rights is put into play.The problem is that the most honest answers to those questions will, more than likely, lead to a conflict and contradiction in the initial argument about fetuses deserving human rights.
