This behavior goes on in ALL denominations. That's why we are admonished to look at their fruit and not what they claim. Most so called mainline denominations are the most liberal when it comes to abortion, fornication, homosexuality, ect. I would say the Evangelicals are the most conservative. You can, however read about the preacher running away with the piano player in almost any berg in the US. The priests sodomizing alter boys and Methodists marrying gays, is all in the mix today. I know many of the so called "rock player" churches that have some of the most wonderful Christians I've ever met. There is wheat and tares, goats and sheep in almost every church I've ever seen. A person that claims Christ and continues as a "sex symbol" is just lying. She hasn't met Jesus and He doesn't know her. Anyone can claim anything.
Oh, and PS.
The verse that says we are not to judge means we are not to judge someones SALVATION. We are commanded, however, to judge SIN. I can't know if you will repent and turn from your wicked ways until you die, however, I can tell anyone that fornicators and lairs, thieves, murderer's, ect, will not see the Kingdom of God. If you repent before you die, you are washed as clean as Jesus and your sins are no longer yours. If I said you are going to Hell, I would have judged you wrongly. Sin is still sin however.
The main problem is that we have not, as RF said, learnt to forego the temptations of the flesh. We don't learn the spiritual fortitude that comes from some denial
And it's not only the religious -- this is shown in careers where kids who can't fathom the concept of "resist for now so that you can get more tomorrow" don't succeed
