Fetuses cannot be considered alive unless they can survive outside of the womb. And since they aren't technically alive until they are able to do so, it is not the slaughter of babies, since they do not develop brain activity until very late stages of pregnancy. Even then they are not even considered conscious. Wanna know why you can't remember very much of your early childhood? It's because your brain was still developing, several
years after being born.

And like tanan stated, if you were in a female rape victim's shoes and you were pregnant with the assailant's child, would you rather be burdened to raise a child that reminds you of that horrific time for 18 years? Or have it surgically removed by a doctor that went to medical school for close to a decade? Clearly the second choice. And who knows, maybe your medical insurance will cover the surgery.
