—The woman is refusing the use of her uterus, just as she can refuse the use of her kidney or bone marrow or blood to anyone.—
The examples are simply not the same. The only way to make them be the same would be for someone to ALREADY be using her kidney or marrow or blood: and for her to kill this person in order to get it back.
—The fact that technology at this point entails the death of the fetus when it’s removed, doesn’t change the fact that the woman still has the right to choose how her body is used.—
Where does this “right” come from? Why is it superior to the right to life of some other being that needs to be killed in order for the woman to again be free to offer or retract her body’s use.
Let’s say that a woman has offered to donate a portion of her liver. The peson getting it has had their old, crippled liver removed for the proceedure, and it has been destroyed. The woman has had a portion of her liver removed already, and they’re getting ready to put it in the other guy when, all of a sudden, the woman decides she wants it back. Is that her right, now that she’s agreed to the proceedure, and it already proceeded past the point where the man will die if it is not completed?
You might say that normally the woman would NOT have agreed to the proceedure: that its more like she wakes up to find it at the stage I describe. But that’s not what you are arguing: you’re saying that she can change her mind at any time even after already deciding to become pregnant.
The fact that you can imagine “technology” one day being able to house a safely expunged fetus is utterly beside the point: that’s not the situation we face now.
—She no longer wishes to nourish a fetus, she no longer has to.—
But the only way to stop the process is to kill it. She can’t even just “stop nourishing it” and let it die. She has to have someone go inside her and tear it apart to remove it.
—I fail to see what that has to do with her right to dictate how her body is used.—
States are constantly putting restrictions on how our bodies are used. States can draft your entire body off to die, but they can’t prevent you from killing a fetus inside you for a few months?
—I’m sure the death of a child due to leukemia is not pretty either, but that doesn’t mean the child’s mother is forced to undergo bone marrow transplants against her will.—
The mother in this example doesn’t have to knife the child in the heart to avoid the having the proceedure be done to her either, so the point is irrelevant. The marrow has ALREADY been given (or, if it made sense, in the process of being given): the mother is demanding it BACK. That’s just not the same thing.
