Hold on a sec, crash...
I would love to continue the historical/communist/athiest stuff all day, but i'm getting tired. Plus, Ringo and Nosyned said that I should reaspond to the OP, and I promised I would to another poster. I am a man of my word, so here it goes....
Should it be allowed for people who voluntarily commit incest to recieve abortions. When it comes to having the child have such medical issues and pain, misery, and mental anguish of a kind that would make the child's life a living Hell, then yes I would allow an abortion. That goes too for a couple who are not inbreds that have the same issue with their child.
But if it was just two voluntary inbreds and the child either had minor or major medical issues (though far less severe than what I described above)then I wouldn't allow it. If a normal couple cant get an abortion, neither should an inbred couple, at least unless the medical issues involved are too horrifying to fathom. And in that case an inbred as well as a normal couple should be allowed to have that one preformed.
As for rape: No, I dont think that abortion should be allowed there. After all, even with that you can still choose to love the child unconditionally, even though it was concieved in a dispicable way (Koine Greek: "Agape", meaning "unconditional Love")I dont think the unborn child here needs to suffer just for the way he/she was concieved. The rapist on the other hand needs to be hanged by his &*#@ and burned with blow torches for the punishment.
BTW: you do have a point on the "Eugenic position" that some anti-abortion activists take on this. Kudos
