I realize this is an old topic, but just giving my 2 cents.
In my opinion, If you examine state laws (at least here in the US since I know not everyone is from the US), most states have laws against killing unborn children (fetus). For example, California, who is a very strong proponent of abortion, makes it illegal to murder a fetus (under penal code 187(a)), and many other states who support abortion have similar laws as well, but under these same laws, the States exempt the murder charge if it is related to abortion. If f we look at the murder of Lacy Peterson, her husband, Scott Peterson, was charged with and convicted of double homicide for murdering her and his unborn child (fetus) under California law 187.
So, there is really no debate as to the deliberate termination of a child (fetus) since it is evident that many States including those who strongly support abortion recognize the deliberate killing of a fetus as murder. The debate however, is with the individual committing the crime:
If a father kills his unborn child, this constitutes a murder charge by such laws. If the mother kills her unborn child, this is still classified as murder but the law exempts it as abortion. Both result in the termination of the child (fetus), it just depends on who does the killing. If it is the father, it is murder, but if it is the mother, it is called “CHOICE” ? why is that? what's so different between the two scenarios? is it solely based on who decides the death? is it really that simple?
just my thoughts on the subject
