You don't let them get sued if they lose a kidney to a vicious mauling by their pet crocodile.
I liked this analogy!
However, pregnant women may require a special case. Unlike kidney patients, who can continue on dialysis & get a different donor, fetuses cannot be...transplanted into another body (QUASI-METAPHOR) without the invasive violation of the woman's bodily rights. They are quite literally trapped with the mom who's giving them life-support, even when they no longer truly need it.
Leafsnail also stated that even something as unevenly-balanced as a Narcam injection shouldn't be allowed.
Meanwhile, 'not taking adequate care of her body' ranges from skydiving to deliberately poisoning/hurting herself in an effort to kill a fully-grown baby.
If the baby has personhoood, the far end of that spectrum makes the mother a criminal.
Does being conceived magically make the embryo a person? Does hitting 22 weeks magically make the fetus a person? There's no easy answer to this question. However, this is all completely and utterly irrelevant to my argument - I do not care when someone "becomes a person". I care about letting women have control over their own bodies, and making sure that they are not arbitrarily put in danger or violated just because they're pregnant. Once the child has left the woman's body (by any method, I don't know why you thought any of those examples would throw me for a loop) this bodily autonomy argument no longer applies.
That's not what ex posto facto means.
This is a really stupid argument, I don't think you can honestly believe it works. When an embryo or fetus is within the womb it's entirely dependent on the mother's blood supply for survival, just like all the other parts of her body and unlike those silly examples you're giving. If it's something that is using your heart, your lungs, your blood to survive then it is part of your body (if you're about to respond with some stupid parasitic example: yes, I have no problem with people removing parasites from their bodies). This is obviously not the case after the baby is born, the umbilical cord can simply be severed and the baby will survive without relying on the mother's organs.
The 22-weeks bit is based on fetal brain activity.
Functional maturity of the cerebral cortex is suggested by fetal and neonatal
electroencephalographic patterns...First, intermittent electroencephalograpic
bursts in both cerebral hemispheres are first seen at 20 weeks gestation; they
become sustained at 22 weeks and bilaterally synchronous at 26 to 27 weeks.
I favor 'brain-birth' and 'brain-death' when it comes to personhood.
'When the baby has left the woman's body' is the hangup point when granting personhood.
What's the definition for 'birth'? When it's no longer enveloped? When it's no longer physically connected?
Perhaps both? But then what about fingers & toes- they're not exactly enveloped. What about skinned fingers & toes? What about finger-bones only held together by ligaments? What about fingernails & hair? (skin-envelope gone, muscle-envelope gone, circulation gone)
Is the child still a part of the woman's body when it's partially free, on the way out, or has it achieved personhood (even though it's still mostly enveloped & still physically connected)? If it's a part of her body at that point, could she kill it without consequence?
Could a crazy lady (or man) with scientist friends grow a living sheath around a block of C4 and have the same sacrosanct bodily rights?
Gah, ok yeah maybe I did use it incorrectly :I (expostfacto)
oh hey, on c-section risk:
Risks[edit]
Adverse outcomes in low risk pregnancies occur in 8.6% of vaginal deliveries and 9.2% of C-section deliveries.[4]
Mother[edit]
In those who are low risk the risk of death for Caesarian sections is 13 per 100,000 and for vaginal birth 3.5 per 100,000 in the developed world.[4] The UK National Health Service gives the risk of death for the mother as three times that of a vaginal birth.[10]
