Well actually animals do carry on in that way. Many times they mount each other to show dominance, regardless of sex, or for socializing in some species. Some pair-bonding animals make homosexual pair bonds.
But surely what happens among animals commonly or uncommonly is irrelevant.
Cannibalism, infanticide, theft, rape and coprophagy are also natural among animals, depending on the species, and might not be aberrant at all. None of that has anything to do with what is proper and moral for humans.
I do not agree. Show me. I think that is Bull $hit . I can’t find any instance of queer animals except human mentally ill. I also attribute it to satanic indwelling of the human spirit to separate you from God. Show me a couple of queer lions?
You’ve never seen a dog, either sex, fixed or unfixed, hump another dog or someone’s leg?
I didn’t take any pictures of one of our rabbits mounting his brothers and both his parents but he was persistent enough that he had to be separated.
You could google bonobos, dolphins, and zoo penguins, but what would be the point?
My point is that we don’t take our morality from animals, or even from what is natural in humans - our fallen state.
