Might be important to add the actual story of "Sodom and Gomorrah"

1st Scripture Used Often to Condemn Homosexuality: GENESIS 19: 1-13
“The Destruction of Sodom and Gomorrah”
(NIV) 1The two angels (a) arrived at Sodom (b) in the evening, and Lot was sitting in the gateway of the city. When he saw them, he got up to meet them and bowed down with his face to the ground. 2“My lords,” he said, “please turn aside to your servant’s house. You can wash your feet and spend the night and then go on your way early in the morning.”
“No,” they answered, “we will spend the night in the square.” 3But he insisted so strongly that they did go with him and entered his house. He prepared a meal for them (c), baking bread without yeast, and they ate. 4Before they had gone to bed, all the men (d) from every part of the city of Sodom—both young and old—surrounded the house. 5They called to Lot, “Where are the men who came to you tonight? Bring them out to us so that we can have sex with them (e, f, g).”
6Lot went outside to meet them and shut the door behind him 7and said, “No, my friends. Don’t do this wicked thing. 8Look, I have two daughters who have never slept with a man. Let me bring them out to you (h) , and you can do what you like with them. But don’t do anything to these men, for they have come under the protection of my roof (i).”
9“Get out of our way,” they replied. And they said, “This fellow came here as an alien, and now he wants to play the judge! We’ll treat you worse than them.” They kept bringing pressure on Lot and moved forward to break down the door. 10But the men inside reached out and pulled Lot back into the house and shut the door. 11Then they struck the men who were at the door of the house, young and old, with blindness so that they could not find the door.
12The two men said to Lot, “Do you have anyone else here—son-in-law, sons or daughters, or anyone else in the city who belongs to you? Get them out of here, 13because we are going to destroy this place. The outcry to the Lord against its people is so great that he has sent us to destroy it (j, k, l).”
