You make a very valid point.
I am well aware of the rarity of third semester abortions and the reasons that almost all are performed. I *do* have a concern that the state or an individual could compel an abortion in the third trimester. It has happened in China. I've had a friend who was compelled to have an earlier unwanted abortion by her then spouse. I tend to look for unintended worst case scenarios...
I would further agree that third trimester abortions must be allowed to happen, also for whatever reason. Of course most of this arises from my decidedly abnormal view that "life" of the kind that is invoked in the sentence "life must be cherished and respected" doesn't start until the people to be involved with caring and nurturing for that specific life have consented to do so. As humans are brought to consummate their consent to this being a life, through their contribution of care (and through the gateway of consent of primary care givers), that is when a life becomes invested. To terminate a life with agency so vested with the consent of the involved, would make those involved "humans who have betrayed the trust of a life they consented to care for".
Now, maybe it's just me but that is fairly clearly in the circle of "bad faith".
It is that moment of consent that makes all the difference in the world, not for sex but for keeping it.
I'm still going to maintain that the geometry of that moment of consent says a lot of the person making that decision. It's undeniably their decision as the primary caregiver at that stage to not consent, whatever that means to the parasitic life inside them.
I definitely believe that third trimester abortions must be allowed.
My issue is that the must NOT be compelled, nor at any stage of pregnancy.
The ONLY valid decision maker is the girl or woman herself, except in instances where she is medically so compromised that she cannot make such a decision (I.E. she's comatose or something similar) and where terminating the pregnancy is less traumatic than continuing to birth. Medical providers can ethically decline to perform an abortion but they cannot compel an abortion if the mother is able to participate in decision making. (Example where a medical provider could make the decision: The mother has been so injured in an accident that she is unconscious and that to attempt to continue the pregnancy would harm her)
Other parents and prospective caregivers have a say in whether they wish to raise the child but not in whether the child is born.
A fetus is not a parasite.
A parasite is an organism that lives in or on an organism of
another species (its host) and benefits by deriving nutrients at the other's expense.
