I don't quite have that position; I don't assert that a fetus necessarily has a right to life. My position is that since the woman's bodily autonomy would trump the fetus' rights if it had them, the question of whether the fetus has rights is irrelevant to the question of abortion.The problem I have however, is with people who admit that even when a fetus has a right to life, still abortion is acceptable because autonomy>life. These people think that abortion is okay even up to the day before the child is born. For me this type of argumentation conflicts heavily with the moral intuitions we have today.
A problem with your analogy: the mother has other options available, such as giving full custody to the father or handing the child off to Children's Aid. The rights of the mother and the rights of the child aren't actually in conflict.Let me present an example. Let's say I am a mother and I have an infant. Now, while this infant is not inside me, they are still dependent on me for survival. I must sacrifice a portion of my income in order to buy food and other necessities for that infant (i.e my right of property is being disrupted in a sense). Also, as a mother, I also have to give my breast milk to that infant (if no other source is available) for her to survive. Now, would it be legally acceptable for me, to go out into the backyard and shoot my child as a means to restore my rights (of autonomy and property)?
A better analogy where the rights of the parent and child do come into conflict like they do during pregnancy:
A child is diagnosed with leukaemia. Without a bone marrow donation, he'll certainly die in a few months; with a bone marrow donation, he could live until old age.
A wide search is made and the only matching donor that can be found is the child's mother.
... but the mother doesn't want to do the bone marrow donation. Would it be legally acceptable for her to refuse to donate?
Yes. Absolutely yes, regardless of her reasons.
Regardless of whether her reason for refusing is that she's afraid of the risk to herself, or that she can't be laid up when she has other kids to support, or she just hates the little cancer-ridden brat and wants to be rid of him, it's legally acceptable for her to deny the use of her body to her son, even if the boy will certainly die because of it.
