True, Jesus never specifically mentioned gays. But he DID mention Sodom.
Lk. 17:26-30: “As it was in the days of Noah, so it will be in the days of the Son of Man; they were eating and drinking, marrying and giving in marriage up to the day that Noah entered the ark, and the flood came and destroyed them all. Similarly, as it was in the days of Lot: they were eating, drinking, buying, selling, planting, building; on the day when Lot left Sodom, fire and brimstone rained from the sky to destroy them all. So it will be on the day the Son of Man is revealed.”
And we all know why Lot left Sodom before it was destroyed.
Gen. 19:4-5: Before they went to bed, all the townsmen of Sodom, both young and old - all the people to the last man - closed in on the house. They called to Lot and said to him, “Where are the men who came to your house tonight? Bring them out to us that we may have intimacies with them.”
