Annie:
Let’s don’t. Before a new analogy is entertained, let’s solve the old one.
I do not assert that the unborn have more rights than do their mothers, only that they do have the right not to be killed.
Actually, that is exactly what you do.
The zygote, blastocyst, fetus is an intruder into the woman’s body. The woman is “supposed” to have her life interrupted if she does not want to accommodate the intruder. That means losing her right to self-determination, just to allow the gestation of the zygote.
But the question is even more problematic. Let’s analyze this scenario.
There is an accident, and someone (person “A”) is responsible for the accident. Not criminally responsible, because the accident was
just an unlucky set of circumstances. The other party (person “B”) cannot survive unless they are connected and the bodily resources of person “A” are used to sustain person “B” for nine months. At the end of nine months they will be separated and person “A” will only be financially responsible for person “B”’-s life, for about 14 - 18 years. No sane court would accept this solution. The loss of person “B”-s life may be regrettable, but it does not justify the interruption of the life of person “A”.
