I insist that an adult pregnant woman, for example, is a person. I think we all agree there.
Show me where I stated it isn't. Also, show me a person who has eaten all types of meat and/or wants to eat all types of meat.
a miscarriage(abortion), is the act of killing the organism, which is wrong.
Why is absolute morality only absolute sometimes and relative some other times?
That says more about us than it does about him honestly. Fact is, even if Trump loses (an apparent coin flip at this point) it'll only be a matter of time before the next lunatic comes in that people will find reasons to support. It's happened before in Germany, it's happening now, and it will happen in the future.
Not everyone consider meat as food, nor does everyone who eat meat as food consider every kind of meat as food.
Did the mother kill all the zygotes/embryos/fetuses that were miscarriage? Was the mother wrong for having miscarriages since, by your definition, it's the act of killing all those organisms?
That's been answered, repeatedly. If you think that the cyst is as valuable as Mrs Smith, then there is something extraneous influencing your evaluation.
So, by your logic, you are saying a brain dead child is not a human being. Is that right?
You can if you want. That's your choice, and it certainly has no moral relevance. An organism just is the physical stuff that it's made of, and that physical stuff is what it is regardless of what, if anything, we call it.
When it's a zygote call it a zygote. When it's an embryo call it an embryo. When it's a foetus call it a foetus. When it's a baby call it a baby.
The idea that there must be some label that names/describes it from the moment of conception to the moment of death, and that the existence of this label entails moral facts about, is mistaken.
You might as well ask when an embryo pops into existence. It doesn't.
No, we've shown with examples that the life of a zygote pales in comparison to the life of a person. For example, if an orphanage and fertility clinic with x amount of zygotes (where x is whatever huge number you want) are on fire, you save the orphanage. In a trolley car situation, you run over x zygotes to save a child (again, where x is any huge number you want).
You're not making any sense. You claim that moral worth (and rights) are not properties of objects but "a status we afford or ascribe to them" but then suggest that whether or not it is wrong to kill a human is independent of whether or not we afford or ascribe moral worth (and rights) to them.
Do "so-and-so has a right to live" and "it is wrong to kill so-and-so" mean different things to you?
Both humans and flies are living organisms. You seem to be claiming that it is wrong to kill (innocent) humans but not wrong to kill (innocent) flies. You are judging the morality of killing a living organism based on its physical characteristics (specifically in this case the physical characteristics that determine its species).
So why is it wrong to judge that it is wrong to kill some humans (e.g. babies) but not others (e.g. zygotes) based on their physical characteristics but not wrong to judge that it is wrong to kill some living organisms (e.g. humans) but not others (e.g. flies) based on their physical characteristics?
Zygotes don't deserve anything, and so neither deserve to live nor deserve to die.
Then what is there to argue? Pro-lifers ascribe moral worth to zygotes and pro-choicers don't. There is no objective fact-of-the-matter that determines one group to be correct and the other incorrect.
But not wrong (and stupid) to judge the moral worth of an organism based on the physical characteristics that determine its species?
False dichotomy.
I didn't say that they deserve to die. I have only said that we ought kill zygotes if it saves babies and that it is acceptable to abort a zygote.
What is the distinction between who someone is and what something physically is, in particular with respect to zygotes? You're the one who often argues against anything like a soul or folk psychology and reduces everything to base biology.
But again, you haven't answered the question. Why is it wrong to judge the moral worth of a human but not the moral worth of a non-human? You're engaging in speciesism without even attempting to justify it.
Well now we might be getting somewhere. Are you suggesting that a living organism has moral worth if and only if someone sees moral worth in it?
That leads to problematic scenarios, such as what if I see moral worth in cows or the serial killer trying to kill you, or what if the pregnant woman doesn't see moral worth in the zygote growing inside her but some random kid half the world away does?
That does not address my point. I'm not interested in sentiment (unless you want to argue that morality is sentiment).
You claim that all humans deserve to live, but then must also accept one of these:
1. No non-humans deserve to live
2. Some but not all non-humans deserve to live
3. All non-humans deserve to live
If you accept (1) or (2) then you accept that it is appropriate to weigh the moral worth of living organisms. I don't see why weighing the moral worth of individuals within a species is any less disgusting than weighing the moral worth of species within a genus (or higher up in the taxonomy).
And I'll add, you already accepted with the trolley problem that the lives of five zygotes are worth less than the life of one baby, so why the about-turn?
Oh, there's that infamous phrase from the Jan 6 speech, "fight like hell". @NOS4A2 likes to interpret that phrase as being in the context of campaigning for an election, "a hard fought campaign". Now we see the intended context very clearly, to fight after the election, to subvert the legal outcome. Of course, that was already obvious to anyone but NOS, because the Jan 6 statement was nearly two months after the election.
As established by the trolley problem, the moral worth of a human-as-zygote is less than the moral worth of a human-as-baby (and in fact, the moral worth of five humans-as-zygotes is less than the moral worth of one human-as-baby).
The moral worth of a human-as-zygote is equivalent to the moral worth of a plant.
I think it's not wrong, or at least negligibly wrong, or at least less wrong than forcing the mother to carry the child to term and birth it (much like it's less wrong than allowing a baby to die).
I didn't say it's right. I said it's neutral. The moral worth of a zygote is negligible, as shown by the trolley problem.
I misread and thought you were asking about me going back in time and then someone terminating my grandmother's pregnancy, and that it would be a Marty McFly in Back to the Future situation.
But as for the question as asked, that really depends on how time travel works. Does the future still exist in some sense but changes as the past is changed? That would change my answer. If the future doesn't exist then no, it wouldn't be wrong to terminate the pregnancy (but it may be wrong to have gone back in time as that would have erased what was the present and is now the future).
And as shown by the trolley problem killing five zygotes is less wrong than allowing one baby to die. Killing ten million zygotes is less wrong than allowing one baby to die.
The moral worth of one zygote is so negligible that killing it is less wrong than forcing a woman to carry it to term and birth it against her wishes.
That depends on whether or not killing the zygote in my grandmother's womb would kill me and my mother, because killing me and my mother would be wrong.
