Most Christian guys admit porn is wrong, so i'm not sure what makes it so special that Chip said it. Being addicted to porn does not mean you approve of it. Many Christian men who are addicted to porn want to be free from it, and acknowledge the wrongness of it.
I think the area of most denial is among women, not men. Many Christian women are 'romance' addicts. Whether its unrealistic expectations of knights in shining armor sweeping her off her little princess feet, living a lifetime of perpetual adoration of her loveliness. Or whether it gets into softcore porn. Many women feed themselves with exaggerated ideas of romance, leading to unhealthy expectations of real life men. Yet so few women will admit to thinking that way. And they feed these ideas through books, magazines, movies, etc.. it looks less harmful on the outside but is actually quite damaging.
