Yet a fetus also has rights. In many ways their rights are similar to a dead body, and even closer to someone believed to have no upper brain activity. In both cases their is a legal guardian that is allowed to make decisions for them, including when to remove them from "life support". Someone other than the legal guardian making that decision is considered murder.
And as I point out above, there is a legal guardian to make their decisions. In the case of the fetus, the mother is always the guardian. After birth, the father becomes a legal guardian, as well (though only if the parents are married).
Yes, the closest relative -- just as the closest relative of a fetus (the mother) is given those rights with a fetus.
No; actually, as you pointed out, this would depend on what the legal guardian wants. While we do not allow dead bodies to be kept in public for long after death, funerals are one such time that they are paraded (though the legal guardian typically tries to keep it respectful. There has also been the
Bodies... the Exhibition which has paraded dead bodies.
And again, the same is true with fetuses. Just that they were never considered "alive", as society defines it.
Actually, this isn't really true. What rights the legal guardian has as compared to the will varies from state to state, in many states the legal guardian can actually override what is stated in the will. Beyond that, the legal guardian can elect to remove someone from life support depending on the circumstances (such as brain death) regardless of what the will says.
Actually, this isn't necessarily true. Beyond the fact that there are many who never write a will or select a legal guardian, in which case the closest relative is selected by, children never are able to select their guardian or in what circumstances they choose to live or die.
Instead, the parent(s) is automatically the guardian and is allowed to make all decisions for the child -- the child has no say at all.
Again, as I've shown, an unborn child does not have its rights taken from it. In fact, it is treated pretty similarly to a child that has been born. If a child depends on life support to live, it is the parents who make the decision on if the child should remain on life support. In the same way, a fetus is on life support, cannot live without life support, so it's mother (who is the legal guardian and is providing the life support) makes the decision of whether the fetus should remain on life support.
I do recognize the unborn have rights. We don't allow mothers (again, since they are acting as life support) to do things that would endanger the child, just like we would not allow a child's legal guardian to do things that would endanger the child (even if it is on life support). We don't allow others to harm the mother in such a way as to harm the baby, if they do they are charged with crimes against both the mother and the fetus. But, like a child on life support, it is allowed to be removed by the legal guardian -- though it is a crime for someone else to remove life support without the legal guardian making that decision first.
