The “I Kissed Dating Goodbye” author was a guy named Josh Harris. He’s an interesting fellow. He wrote that book in his twenties and, even as a young man, I remember thinking it was complete nonsense. He became a darling in Christian circles though. Youth groups everywhere were reading his garbage.
A few years back, he realized that the book, and his association with Christianity was costing his marketing business customers, particularly among the pervert crowd (LBQ whatever). So he went on an apology tour, embraced the perversions he once despised, divorced his wife, and then renounced not only his book, but Christianity as a whole. It got him a few headlines for maybe a week, but he never regained that fame he once had. He once again faded into obscurity never to be heard from again.
