It is wrong to excerpt PART of morality discussions from the Bible. In fact, that particular story goes into a discussion of "but what if there are innocents present" and then further "how many innocents provide protection by their righteousness". The decision from the story is that TEN would be sufficient (but that there weren't that many).

BTW, we tend to mistake much about that story. The "sin" of the towns being not so much HOW the strangers were to be molested but that they were to be molested (it's not the only instance in the Bible of towns being destroyed for not acvcording travellers "safety of camping in the square"). Likewise we tend to mistake traditional Middle Eastern manners and speech patterns. Lot isn't really offering his daughters instead of the strangers, he's rebuking the townfolk (and by their response to his "offer" it is clear that they understand this).

Genesis 18.

Spend a little time reading the Bible and you'll realize that anyone the writers didn't like we made out to be practicers of incest, masturbation, homosexuality, drunkenness, unsanctioned writings, other religions, and just about anything these desert-dwellers didn't take a shine to--and that very often these "vices" were used as an excuse to exploit or abuse them in some way. I wouldn't be a bit surprised to find that, if we were to take a time machine back to old Sodom and Gomorrah, we'd find two liberated towns that were more creative, fun and free-thinking than anything the heat-struck Bible-thumpers could handle.

So let us pray--for the misunderstood towns through history, where we had so much fun and created so many wondrous things such that the ignorant and the envious were convulsed with anger and violence. And let us not cease to celebrate life in our big, passionate, pulsating cities, filled with people who choose to congregate, not retreat into caves and bushes, out of our love of humanity and humanism.

People do not congregate in cities out of 'love of humanity and humanism' but out of necessity, laziness, or greed.

You're absolutely right. I'm far too lazy to invent plumbing, write, type, bind and print "Anna Karenina," weave my own clothes, build instruments and play 100 parts in an orchestra, invent and produce antibiotics, and invent and build this computer I'm using to communicate with.
But now that I have these things, I think I'll move to the sticks. But the rest of you, stay in town, so I'll have someone to complain about.
