I think abortion should mostly be illegal, but if life begins at conception, is a fertilized egg in a test tube a human life?
If a nurse drops the test tube, is that manslaughter?
If a mother has a fetus with no head, should she be forced to deliver it?
A fetus with no head?
Do explain.
Yes --- assuming, of course, that it was conceived from a human ovum and a human sperm. If canine gametes were used, it would be a dog. If feline, a cat. If equine, a horse. That's indisputable.
"If a nurse drops the test tube, is that manslaughter?"
If negligence or criminal intent are involved --- the same as if she dropped a preemie. That's by the way, one of the big reasons why babies should never be conceived in vitro. It exposes them to hugely magnified risk. Humans should be conceived only in vivo.
"If a mother has a fetus with no head, should she be forced to deliver it?"
If she has a fetus with no head, the fetus (actually, embryo) will perish very early (probably even before pregnancy is detected), and very naturally and probably very easily. No need to worry about "delivery" of headless babies; no need, either, to induce an abortion.
