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...
