Ethics of procreation: Consider a scientist that could grow humans knowing that two thirds of them would die after suffering short lives of terror and extreme deprivation, but one third of the lives he could produce in this manner would survive to a productive adult life. We would think that if he were to create extremely bad lives rather than good lives, he would be committing Mengalian atrocities, or at least, that is what I think the general intuition would be. But there are conditions in which people procreate knowing that their children will suffer short and extremely bad lives, in subsistence conditions, where two thirds of the children they produce will suffer in this way. To ensure the two cases are analogous, suppose that the scientist creates these lives only to ensure his genetic continuation, his security in old age, or out of economic necessity, and will stop producing lives only when he has two viable children to support him and work in his lab. Can one context of procreation be plausibly...

Based on your description of the scenarios you're envisioning, I'm not seeing any inherent moral difference between the scientist and those who procreate children in the 'ordinary' or 'natural' way. Whatever moral reasons seem to weigh either for or against procreating children knowing that there is a high probability they will have "short and extremely bad lives" apply equally to the scientist as to anyone else who procreates under the same conditions. Perhaps you're seeking to highlight that the scientist 'grows' humans outside of a "natural context" as a morally significant factor that makes his procreative acts morally worse. There I'd have to say that while his creating the offspring in some sort of artificial or 'unnatural' way adds to the 'ick' factor, but it's hard to see how there's any moral difference there. No doubt many people attach some moral significance to 'naturalness' when it comes to procreation. They might argue that somehow natural procreation isn't subject to the same moral...

Is it a valid argument that it is okay for someone to be homosexual because they were "born that way?" This argument seems to lack merit to me, and I believe the reasoning should be that there is nothing morally wrong with it aside from having certain religious conflicts. Pedophiles could be born the way they are, but nobody condones their actions, because there is something arguably wrong with what they want to do. I just seek another point of view on these issues, and possibly a few examples of things that may in fact be morally justified simply because one was born a certain way.

I'd be surprised if there were sound arguments for the immortality of homosexuality, but I agree with your suggestion that whether or not LGBT persons are 'born that way' or not cannot provide a sound basis for the immortality of homosexuality -- nor can it provide a sound basis for its moral permissibility of homosexuality either! Your remarks about pedophilia suggest why such arguments are unsound: That a person is born in some way does not imply that actions they perform because they were born that way are not wrong. If (as seems likely) pedophilia is harmful to children, that it is wrong even if pedophiles can't refrain from having sexual desires directed at children. 'He/she was born with property P; he/she does X because he/she has property P; therefore, X is not morally wrong' is not a valid inference. But perhaps this misunderstands the force of the 'born that way' claim. Perhaps the force resides not in the idea that being 'born that way' makes a person's actions morally permissible but that...
