"Embryo selection"—is that a euphemism for "murdering any unborn child that doesn't have all the "right" genes? Because if so I think your definition of "people's lives" must be very different from mine.
Definition? Do you mean no limits at all up to and immediately prior to birth? I'm not sure you'd get unanimity on that. That implies a few seconds separating legal permission to kill from infanticide.
I agree with your position, but it is no less polemical and ideological than the comment you are responding to.
> an embryo is not a child and you cannot murder an embryo
It is not obviously and axiomatically true that embryos are not human (I'm assuming the previous comment meant human and not child). Many people think that they are, which is the source of the disagreement. It probably is fruitless to have this conversation on HN, but you shouldn't just assert the opposing position as if it were settled when it is anything but.
> but it is no less polemical and ideological than the comment you are responding to.
I beg to differ. I don't think that using dictionary definitions to make ones arguments can be counted as polemic (as in; to use contentious rhetoric). I might be wrong though.
> I'm assuming the previous comment meant human and not child
No, I actually meant 'child'. An human embryo is - obviously - human. No discussion about that. A human embryo is not a child - the definition of that is also pretty much settled, I'd say. (At least from a scientific point of view.)
But maybe I didn't clearly state my case, thus the misunderstanding.
The point I'm making is as follows. Embryos are not children and thus they are not persons. Just as I cannot murder my toe (it might be human, but it's not a person) I cannot murder an embryo.
Quotation needed. Outside of religious circles there's very little debate about this. Scientific consensus is that fetal viability is considered to begin at 23 or 24 weeks gestational age. That's long after the embryo stage.
Just to make communication easier; are you aware that there's a difference between embryo and fetus?
> You also don't have any definition with a clear line when this switch from non human to human happens.
I never proposed that a embryo is not human. But we can talk about the line dividing persons from non-persons, if you like.
Many (including myself) consider abortion to be murder even before fetal viability.
> Outside of religious circles there's very little debate about this
Do you live in the US or Canada? Almost every other country, including almost all of highly secular Western Europe, bans abortion before at no later than 17 weeks (https://en.wikipedia.org/wiki/Abortion_law).
It's hardly a polemic when it is a question of existential importance- what does it mean to be human, when does a human begin to exist, and at what point does a human have rights?
Embryos are without a question human. So is my little toe. The question is whether they are persons.
The importance of the topic doesn't make it impossible to be polemic. I can talk about a very serious topic and be polemic and I can also talk about a trivial matter and not be polemic. The question of polemic is decided by contentious rhetoric.
Equating embryos with children and abortion with murder is polemic.
The question is not are embryos human, the question is whether they are independent human life with their own rights.
I don't think it is polemic to disagree on this point, but it rationally follows that if embryos are unique life forms, which are also human, then aborting them is murder.
Personally, I don't agree with that line of reasoning either, but the argument isn't in itself polemic.
Edit: I suppose I should add that I am not treating "human" as a collective noun, the way we might talk about bread or water. "A human" is not merely a little toe, for example.
>> Embryos are without a question human. [...] The question is whether they are persons.
> The question is not are embryos human, the question is whether they are independent human life with their own rights.
I think we are pretty much in agreement what the contention is about.
> [..] the argument isn't in itself polemic.
The argument itself is not polemic. No argument in itself is polemic. Polemic is defined in the language used. I'm objecting the language in which the argument is phrased;
To quote the post I originally answered to:
> "Embryo selection"—is that a euphemism for "murdering any unborn child [...]
The phrasing is polemic for reasons I pointed out before.
