Abortion: 10 years as an atheist and I still don't get it

[The Grand Nudger]

If that's your position then you're not pro-choice.  You fall closer to pro-life on this spectrum.  Well... provided I'm correctly interpreting your grammatically garbled paragraph.

"...is when there's nothing wrong with the child, no compelling reason other than the halth of the child to abort..."

Uh... what?  Is the child halthy or not?  There's nothing wrong with the child other than its halth?  What else do you evaluate in a fetus?  Its math test scores?

The pro-choice position is that a woman can abort her child for absolutely any reason she sees fit.  It's called an elective abortion. Welcome to the debate, here's your introductory pamphlet.

That's not exactly the pro choice position, but the pro choice position is a comment on legality, anyway.  You asked for moral justifications.  

So now you are in favor of allowing a halthy fetus to be aborted?  What the fuck are you even saying?

The same thing I've been saying since I first answered the question you asked.  That there are -many- moral justifications for abortions, from at least three major categories of moral consideration. 

That question was never asked. Remember, this is "sometimes" vs "always."

-and when I remind you that I've already answered this one, will you kick the goalposts a few feet back, or?  

I've given you three categories of moral justification, these three categories describe the breadth of any other moral consideration.  Moral goods, final moral goods, and avoidance.

Try to think of any other thing you consider morally justified, and why.  You'll find that if it can be justified, -even if your justification were in factual error, as it was with the vegan example- it falls into at least one of those three categories.  Since examples and elaboration don't seem to have any use for you, your question could be answered more simply without reference to any of them.

Abortion can be justified in any and all of the ways that any other thing is.

-To answer your question. I acknowledge that the abortion of a healthy fetus can be morally justified, yes, ofc. The health of the fetus isn't the only morally relevant fact (depending on the schema, it may not be a morally relevant fact at all).

That doesn't mean that I would do it or that I would personally accept that justification if it were me making the choice.

In my opinion, your confusion on this issue is down to misunderstandings of key terms you've attempted to employ in support of a position called moral absolutism. You posit that killing life is absolutely wrong. Most of us do not. In an absolutists value schema you'd be asking for the impossible, but in any other value schema you'll find any number of rational and lucid answers to that question that, again imo, better reflect reality.
