Didn´t know about the 2 versions of the S&G story.
But I do know that the whole "give women over to the crowd to prevent homosexual rape" plot device is used 2 times in the bible, apparently they had a problem with plagiarism even back then.
it shows up in the S&G version with the angels, but it also appears in the book of judges, a man traveling with his concubine is taken in by a kind old man, and the male townsfolk come around wanting some male on male action:
the moral seems to be that straight rape is preferable to gay rape.22 While they were enjoying themselves, some of the wicked men of the city surrounded the house. Pounding on the door, they shouted to the old man who owned the house, “Bring out the man who came to your house so we can have sex with him.”
23 The owner of the house went outside and said to them, “No, my friends, don’t be so vile. Since this man is my guest, don’t do this disgraceful thing.
24 Look, here is my virgin daughter, and his concubine. I will bring them out to you now, and you can use them and do to them whatever you wish. But to this man, don’t do such a disgraceful thing.”
25 But the men would not listen to him. So the man took his concubine and sent her outside to them, and they raped her and abused her throughout the night, and at dawn they let her go. 26 At daybreak the woman went back to the house where her master was staying, fell down at the door and lay there until daylight.
