The crazy comes as a package deal, you don't get to pick and chose from God's Law
This is going to cause a lot of societal stress over the next few decades.
If your religion's foundational documents contain a story that's in conflict with what we know about biology and cosmology, and you don't want to reject evidence-based knowledge in favor of religious tradition, you can dismiss the story as poetry intended to credit it all to God.
But if your religion's foundational documents state flat out that homosexuality is a 'sin', and science shows that it's a biological outcome no different from (say) being left handed, that's a lot harder to dismiss. Plus, clinging to it makes you condemn a whole class of people to hell for their biology.
From a sociological perspective, this is going to be very interesting to watch.
