If I read, remembered, and understood correctly, Lot's daughters were not virgins and had husbands who stayed behind in the city, and Lot judged the crowd severely with that suggestion to the point where they might have been cut deep. Then the crowd was angry and threatened to do him worse, but their whole city perished. Why else will they say their daughters were virgins to such people, unless to show them how evil their request was?
