But if life is the most fundamental of rights, and if human life begins at conception (as I believe it does, logically and Biblically), a pro-choice country submits my fundamental rights to popular vote and the whims of others, does it not?
First of all, it does not, because you are not going to be aborted, as you are a person, to whom rights apply. I agree that life is the most fundamental of rights, but rights apply to people, not to fetuses. The question is when personhood begins.
It cannot logically begin at conception. If so, then what of the 1/3 of all natural pregnancies which go through conception, but never implant onto the placenta? If these embryos were persons, then this would be the greatest tragedy in human history. Do you think then, that we should make sure that every embryo that is created successfully implants and is born? It is not logical because no one advocates this, despite the fact being well known to medical science for decades.
Biblically I have already pointed out that the Bible never mention the word "abortion", so how can it be "Biblically" prohibited? The last time I mentioned this, I was pointed to the apocrypha, but whether that represents a Christian view or not, the apocrypha is not the Bible. The Bible heavily hints that killing a fetus is not considered murder. There are many other statements in the Bible that are much more clear than abortion. For instance, the Bible clearly says that women should cover their heads in church. Yet you see no one following this. The reality is, most religious right preachers just make up things that align with the preexisting prejudices and then claim it's Biblical.
