How many righteous cities can you name? None! Consequently it follows logically that any disaster befalling any city on earth is somehow deserved because of a lack of righteousness.
Pretty silly.
Yeah, and this is something that people like Pat Robertson and Jerry Falwell just don't get. God does not punish entire city populations because of brothels, abortion clinics, or lesbians.
This is the same fallacy that haunted many people after Pompeii was wiped out by Mt. Vesuvius. It was believed that it must have been some kind of punishment from the gods for misdeeds of it's residents.
It's interesting to note that the most destructive natural disasters in this planet's history happened before humans even existed. (mass extinctions by climate change, meteors, etc.)
But then again; maybe God punished the dinosaurs because some of them were gay and lesbian.
