How about an 8 minute old single-celled zygote?
Does this single-celled zygote, left unmolested, progress to an 8 week old baby?
No, it lies frozen in a fertility clinic, while the parents decide what to do with it.
If they decide to donate it for research, should they suffer prosecution for murder?
The parents were allowed to draw breath, their offspring must be allowed to continue along the natural path to drawing breath as well.
If you believe differently, that's your right. No point going round and round on this, we'll just have to agree to disagree.
