Lot's daughters were thrown to the mob to be used as hostages to insure that the strangers would not harm the town.
But the strangers did come with the specific purpose as jihad terrorists and they did blow up the town before they left.
"God" did not send fire and brimstone from heaven. Orders may have come 'from above' meaning the top military factions, but nothing supernatural came from the sky.
These terrorists may have intended to act as "the invisible hand of god", but it is clearly evident this town was destroyed by actual jihadists.
Furthermore there is really no evidence that Sodom was a town of homosexuals. The reason preachers use this as an excuse for that dogma of hate hinges on the word "know."
The men of the town wanted to "know" who the strangers were. Well, can you blame them? This was a rather closed community; it was walled. Why would 2 men come at dark not knowing anyone there that they would visit, seemingly having no purpose, and not there to seek shelter from their travels? They were hanging around in the street, surmising the town. Lot was the gate keeper, and therefor had some responsibility for the safety of the town. That was the only reason for his hospitality.
And as for the word "know"...it does not always have a sexual connotation. It was not meant in that sense in this story. The xtain telling of this story has been a wicked fabrication and probably deliberate in its intention of hate mongering and dogma.
