Should we encourage abortions for single mothers because their child might not have a happy life? Should we abort fetuses who have some disability? I'm sure that any of those individuals, once born, would prefer to live regardless of circumstance.
Yes.
> Should we abort fetuses who have some disability?
If the parents are unwilling or unable to deal with it every day for the rest of their life, yes.
> I'm sure that any of those individuals, once born, would prefer to live regardless of circumstance.
That's too big an assumption. But, in any case, not being born, and not having a working brain capable of abstract thought and understanding of the situation, nor a way to express it, they don't get a vote.
Im sorry to say but this sounds like Orwellian doublethink.
> By week 6 the mother feels there is no future in the relationship and feels she can't offer the coming child a good childhood on her own.
Are you saying that a woman probably cannot reasonably provide a good life for a child without a man? I mean, even if she can't then this is an extremely tenuous link. I didn't have a good childhood at all and the scenario I was in personally was actually worse than you described but I turned out to be very happy. Even if I wasn't happy it would be worth living. There are also many people in truly horrific situations in the world - in every country.
In good faith and with much respect I am asking you: do you think that the chronically unhappy people of this world should have been aborted before they experienced this world and without their consent or knowledge? Obviously hard to put a number on it but with the kind of scenario you describe, maybe 20-25% of living adult people have been through?
So imagine a situation where a mother and father have a falling out. By week 6 the mother feels there is no future in the relationship and feels she can't offer the coming child a good childhood on her own. I feel if a child is unwanted by the parents, they are more likely to suffer.
So in this sense, abortion can be a form of harm reduction. It does not reduce ALL harm, but reduces the net-harm across all parties.
