I agree that simply saying it is biologically human isn't enough justification. However, your claim the women should have a bodily right to kill an innocent human hasn't been substaintiated either. The fetus has a moral and inherent worth, not because it is simply human, but because of its future capacity of thought, and contribution to society. Simply saying a women has rights therefore she can murder a child is illogical, because where are the violated fetuses rights? The fetus does use the mothers organs but that is because of a nautrally divine process. The fetus is still a seperate being from the mother with a unique code of DNA. Majority of abortions happen after the consentual act of sex, and if you get pregant as a result of that you need to inherit the consequences. It is the same as saying when I get into my car, I inherit the responisbility of vigillence, and if I get into a crash and its my fault because I choose to drive it is in my legal and ethical duties to provide reperations.
