I actually, whole heartedly agree with steen, its rather nonsensical to say a person is not a person because he or she was concieved of via rape or insest or because they have developed some disability (nicely put as medical reasons btw)
we wouldnt say to a born human being.
"your a result of rape I am going to have to terminate you"
"your a product of incest, you have no right to live"
"your disabled, I have every right to kill you since I look after you"
if the premise is that the unborn fetus is a human being and as such a human person, then he/she holds as much intrinsic value as a person outside the womb.
The whole pro life except for.... Is a hypocritical stand point at best that is sending out a mixed message and at worst is sheer condoning of murd....
Either unborn are people and worth the same as born people or they are not
if they are not then, abortion is not wrong in any circumstance even as a form of birth control or as one weird person said for fun
but if they are persons it is wrong in every circumstance except life threatening issues.
