I'd never heard it suggested that SLC was some sort of den of iniquity. All the Mormons I've ever met in person were The Nicest People Ever (seriously). But after just a few seconds research, I come across this:

'The Real Housewives of Salt Lake City' Is Getting Too Evil (Gawker 1/28/2022)

The Housewives world is already full of colorful, bored, evil, rich people. But RHOSLC takes this to a different level, featuring women who are unwell in a way that should not be on camera.

Good Lord, Gawker calls out in all earnestness that the show needs to be shut down? The only words that came to mind were these:

Babylon the great is fallen, is fallen, and is become the habitation of devils, and the hold of every foul spirit, and a cage of every unclean and hateful bird.
