And when does a fetus become a 'person'? No one knows, this is not something that science can address. It is the subject of philosophy, so the only determinant is judicial decree. Under Roe, that was at 22 weeks or so. Until we have a judicial decree on that point (which some states do) we do not have a legally established 'viability'. No one is recommending abortion for a fetus that has reached viability, and is legally decreed as a 'person'. So, before that adjudicated point, there is no 'person' and thus there is no murder, and your statement has no legal consequence. If your reasoning is based on a philosophical or religious view, please understand that even the Bible, in many places, treats the unborn as a commodity, as chattel. so, there is very little in law and religion to support your view, other than your own philosophical stance, which carries no weight in this debate. If philosophy is the basis, then 'whose philosophy'? As you can see, if we go there, the destination is chaos.
Moot point, see above.
