McConnell: One can make a pretty convincing argument, however, that fetuses are persons. They are alive; their species is Homo sapiens. They are not simply an appendage of the mother; they have a separate and unique chromosomal structure. Surely, before beings with all the biological characteristics of humans are stripped of their rights as "persons" under the law, we are entitled to an explanation of why they fall short. For the court to say it cannot "resolve the difficult question of when life begins" is not an explanation.
Here's my claim. If this argument goes through, then you have a Federal case against abortion based on the Equal Protection clause. What is wrong with this claim?
