Book excerpt: In Skipping Towards Gomorrah, Dan Savage eviscerates the right-wing conservatives as he commits each of the Seven Deadly Sins himself (or tries to) and finds those everyday Americans who take particular delight in their sinful pursuits. Among them: Greed: Gamblers reveal secrets behind outrageous fortune. Lust: "We're swingers!"-you won't believe who's doing it. Anger: Texans shoot off some rounds and then listen to Dan fire off on his own about guns, gun control, and the Second Amendment. Combine a unique history of the Seven Deadly Sins, a new interpretation of the biblical stories of Sodom and Gomorrah, and enough Bill Bennett, Robert Bork, Pat Buchanan, Dr. Laura, and Bill O'Reilly bashing to more than make up for their incessant carping, and you've got the most provocative book of the fall.
