it is much more accurate to say that it is a separate human inside of another humans body
Ah, this is 1 step closer.
From this respect (ie. if it is a human) then abortion is murder right? Jus as killing a non-human living being is not murder right? For example killing a chimpanzee is noit murder (in a totally legal sense anyway). But then we have a conundrum...the chimpanzee has a 99% DNA match to humans. The chimpanzee is more intelligent than a living baby (not a fetus). But we have to agree the chimpanzee is not human. So what is it that makes us human? This is the whole crux of the true argument because without the definition of a living organism being human then we cannot classify ending it's life as murder...
