Well its not unnatural, but that doesnt mean its not immoral. But to clarify the reason for bringing up homosexual animals is to refute the argument that homosexuality is unnatural becuase it has no apparent reproductive value. However, since there are homosexual animals we can see this is irrelevant.
No, it's not, and see my comment at the end.
At the same time it also goes some way to refute the religious idea that a humans are choosing to be gay, since if that were true and its unnatural then homosexual animals must also be "choosing" to be gay as well and therefore must be sentient and have a soul just like humans do in order to have the free will to do so. Since if they didnt choose to be homosexual, they wouldnt be at all if we use the same logic.
This is a logically bankrupt argument; you need not have a soul if sentient, for starters, nobody ever said that and a lot of religions have argued some group or another doesn't have a soul at various points.
But leaving aside the philosophical implications, you need not be sentient to "choose" as it were. A lab rat in a maze can go left or right. This is a choice, and it makes one. You can condition an animal (or a person) to do irrational things. Environmental factors need to be examined in these cases, as does the fact that pure random chance plays a factor.
And I asked you before, can you personally choose to be sexually attracted to someone of the opposite sex? Can you even force yourself to be attracted to someone you're not attracted to even if they are of the same sex?
I can't vouch for the latter, but the former? Certainly. I've done it before; several of my relationships have had a "convincing myself" stage. Perhaps I'm strange; perhaps I grew a little too cynical about people in general. Still, it proves it can be done. Equally germane, you can chose
not to be attracted to someone of the opposite sex, and we do it all the time.
Besides, if you're trying to say people are born homosexual, it would be a self-solving problem, as the genes responsible would be eliminated...
Yet as we can see from the rest of the animal kingdom, that is demonstratively not the case.
Is it? The point he makes is valid. It ought to be self-eliminating. But it apparently isn't, which leads to the fact that they must be reproducing, wtfbbqlol and so on.
So maybe we're all a bunch of idiots sitting here arguing about homosexuality in animals when the animals in question were bisexual. We've drawn pretty little pictures in our head in black and white. This is normally considered A Bad Thing, yet here, somehow, we've decided that black and white is shiney and works. We believe it feverantly.
I suspect this to be all delusional.
I think in the end the choice thing isn't wholly wrong, in that in our rush to create the black-and-white shiney-ness (on both sides of the coin here) a lot of people on one side or other
have managed to force down a part of themselves, which perversely proves the point that you
can make a choice at least in a negative sense.
The irony here is that if genetic it may well end up being self-eliminating for humans because of our insisting on that shiney black-and-white duality, thus smacking everyone across the face and "proving" the argument you just tried to refute "correct."
