I don't think there's anywhere in the world today where a mob will demand sex, homosexual or heterosexual.
Haven't you ever heard of people being gang-raped? That could be called a "mob" demanding sex.
But I thought S&G was destroyed because of general wickedness. Exactly what did that mean? Public torture? Rampant crime? Cannibalism? There could have been all sorts of things not mentioned. The only thing mentioned is the mob demanding to have homosexual sex. Actually, it would have been angel and man sex, not man and man. Is that even homosexual?
Seems to me some things were pretty screwed up back then. Since when does a father offer up his daughters to a mob? Did he want the angels all to himself? Since when do daughters decide to get their father drunk and seduce him to have children? And since when does a "righteous" father go along with it? I've never been so drunk that I wouldn't recognize a family member. And if I did get that drunk (and at his probable age), I kinda question the ability to "function". OK, maybe he gets drunk enough to let his inhibitions down. He knows he shouldn't, but, maybe they're doing "things" to him, and in his state he gives in. I know there've been girls I know I should have just left alone, but a few beers later, they're coming on to you, and next thing you know.... OK, I'm not excusing him for incest, but let's say that's how he got duped. If he wasn't too drunk to "perform", he'll probably remember it when he sobers up. If he's righteous, he's going to feel guilty and try not to let it happen again. So, how come when the second daughter gives it a go, he still drinks and gets drunk again? If it were me, I wouldn't be drinking anything around those two after being tricked.
At this particular time, there doesn't seem to have been any written "code of conduct" given to them by God, as the "Bible" hadn't been penned yet. So who's to say what was considered good and bad? Maybe all forms of sex were acceptable. Certainly having sex with the maid (concubine) was considered OK. Multiple wives were OK. Maybe even sex with family members and homosexual sex was considered OK. Maybe the guiding principle back then was something like the golden rule, basically, don't hurt anyone (mentally, physically, financially, etc). That's something everyone should be able to figure out, even without a "law". In the area of sex, consensual sex is usually not harmful, no matter what sexes or numbers are involved. It's all a matter of your upbringing as to deciding what makes it good or bad. Maybe back then, the thing was, "if it feels good, it is good". I might be missing a Bible passage, but we might be assuming homosexuality was part of the wickedness, when it could have been something totally different. In the example, the mob "rape" would be a hurtful act and may have been considered part of the wickedness, but maybe not the type of sex, if it had been consensual.
So.... not knowing exactly what wickness they were guilty of, it's hard to say how we compare. If it was sale of children for food, then I'd say we're better off today. Again, don't know all they were guilty of or to what extent.
