Right to Life trumps your autonomy
Except where it doesn't, such as where abortion is legal, in which case it has been deemed that the mother's autonomy trumps the fetus' right to be born. You're merely expressing your preferences. Noted.
there is no such right to kill another human for no reason or on a whim.
You keep repeating that, but you are clearly in error. There is a right in some jurisdictions, America being one for now, to get a legal abortion without having to provide a reason. Her reasons are nobody's business but her own and those she chooses to welcome into the decision making process.
You mean likes fetuses are made less than human like you have?
Fetuses are fully human, but that is not relevant to the issue of the moral status of abortion just as it is not relevant regarding killing in self-defense, human or otherwise. Also, I would attempt to save a dog trapped in a burning building just as I would a child, the child being no more important just for being human, although I confess that if they were both trapped in the same fire, I would choose to save the child first, but for practical and not moral reasons. I consider their lives of equal value, and both worth more than an embryo's or fetus'.
For me, if it's immoral to abort human beings, it's immoral to abort dogs and cats. Giving humans special status in moral issues is a religious concept that I don't hold.
Nor does it matter if you call the fetus a human being, a person, a child, or a baby. Nomenclature does not define moral status. One's reaction to the thought of an act does, and that applies only to that individual's moral code, not anybody else's.
Here;s an interesting moral dilemma for you. You work in a fertility clinic with dozens or hundreds of frozen embryos, and a fire breaks out. You can choose to save your child that you brought to work with you, or a container with 50 viable embryos, but not both. If you would choose the living child over the 50 potential living child, then you are tacitly stating that you don't consider even 50 embryo to be as valuable as a child. Neither do I.
And I also don't consider a fetus in the womb to be the equivalent of that child for the purpose.of making moral judgments.
Human organs are. They're certainly not canine or ursine.
But I've already explained to you that for me and probably many others, being human is irrelevant to the moral calculus whether we are discussing an organ or an organism.
I point out the consequences of an action and that the solution isn't killing something on a whim
I doubt that many abortions are requested on a whim. I'm guessing that there is an unwanted pregnancy somewhere in there as well, one giving the potential mother more reasons than whim to want to terminate the pregnancy.
And even if the woman were requesting an abortion on a whim, that's her business, not yours or anybody else's. The law says so.
Do note your comparison is flawed as you fail to consider that the subject is about one life within the body of another while your example was of two lives with zero connections to each other.
Irrelevant to the comparison.
Any two entities, processes, or relationships can be compared and contrasted, and there will always be a list of similarities and differences. When somebody offers a metaphor or analogy, the similarities may be more relevant, making it a good metaphor, or the differences might be more relevant, making it an inapt metaphor.
For example, I think that Plato's horse and rider metaphor for the mind is apt, as it puts a more rational element in the role of trying to control the emotions, which may be quite powerful, quite irrational, and resist being reined in. For you to say that that is not a valid analogy because horses have hooves and minds don't is to point out an irrelevant distinction that doesn't diminish the value of the similarities to stand for one another.
The comparison was between forcing a woman to have a baby she doesn't want to deliver to saving the life of another, to forcing somebody to donate an organ he doesn't want to give to save the life of another. Those are the similarities that make the example relevant. The distinction you make doesn't change the moral issue. If one is right, so is the other. If one is wrong, so is the other. You offer no reason to view the two situations differently. They both involve others making decisions for competent, autonomous individuals that affect their bodies. The relevance of the comparisons (similarities) trump those of the contrasts for many people - most I'd bet.
