If I don't think it is a person then I don't value it.
You do not value even those for whom you concede personhood. Once a baby develops to the stage when even you would have to concede personhood based on your nonsense nervous system criteria — and remember, this is well before standard suction-aspiration abortions can be performed — you still endorse his extermination on a "case-by-case" basis.
Clearly, personhood means nothing to you.
