What nobody seems to wonder about is why both the Bible and Quran strongly prohibited gay sex and that idea is so widespread across most of history and most of the world, even today, and even in China which doesn't have a history of those religions. You can't say we know better now because we're better educated when we don't know the reason in the first place. 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.
