I think you might be assuming that the only interpretation of religious text is that they are all-or-nothing affairs, across the board. One of the core tenets to Christianity is the recognition that everyone is going to sin (or not "adhere to the supposed wisdom of the divine" as you put it) and that they will still be forgiven.
What if it's Whiz?
There are some clues. The Bible has the story of Sodom and Gomorrah, which might be a collective memory of societies becoming gay-friendly and promiscuous then being destroyed somehow. It could have been put into a story about God to make it memorable across generations (we do still have the story after-all, and we don't still have the actual history). In Islam, Mohammed said his greatest fear was that Muslims would turn gay. Why was he so afraid of that? Maybe there was cultural knowledge of what too much tolerance for gayness leads to and we just don't have that knowledge in our recorded history.
Not saying I have the answer, but nobody else does either. It's naïve to just look at the direct consequences and say "they're not hurting anybody so it's fine". There might be destructive emergent social phenomena that come from it being widely accepted over the long term. We only have basically 2 generations of data on gay-friendly western society to observe from.
