An interesting concept just came up, one I disagree with, but interesting none the less.
Late term abortions, are usually really euthanasia.
That is, the majority of time they're on non-viable fetuses, or at least, fetuses that are seen to have a less than ideal life. They are done, primarily, on the physically unfit.
Now of course, that line gets somewhat blury, for none of us can accurately see the future. Euthanasia should always be opposed for precisely that reason- because even a diagnosis can be wrong. And that's why late term abortions for something "medically wrong" with the fetus should also be opposed- because it's a final solution for a not very finite problem.
Still, it never occurred to me to look at these types of abortions-because-of-prenatal-diagnosis as Euthanasia before- and it does make for an interesting side discussion. Can even Kermit Gosnell's and Douglas Karpan's infanticide be considered a form of Euthanasia? I think so. Certainly in their minds it was- they were killing those infants accidentally born alive, they even treated lower class women badly, because they didn't see such people as having a viable future.
