You don't think its a coincidence that these scandals keep occuring with these same type of teachers? Baker, Swaggart, Bob Tillman, etc. Seductive prosperity gospel, social gospel(political activism) signs and wonders (Haggard is part of the new Apostolic propehts/vineyard movement- see deceptioninthechurch.com).
This happened because of sin. The sin might reveal that he is not even a true Christian. Imagine that. You can preach a lot of truth but if you do not live by it, you are not the real deal.
You can argue for and against alll those other things and I might agree with some of your arguments. But they are unrelated to this. I've seen people who were none of those things fall into the same sin trap (sexual sin is a biggie). You notice the famous people and tend to want to draw connections. But that's a red herring. This happens because of the unaddressed depravity in his own heart. It isn't because he is well-known, political, tele-evangelist, mega-church pastor, and all the rest. I don't agree with many of the man's religious teachings, but this happened only because of one thing: SIN!
Do you know how many pastors these days have a problem with pornography? If studies are true, a whole bunch of them have a problem with it and they come from all sorts of backgrounds and perspectives. The church has been corrupted by sin. We need to clean house. Even good doctrines are being manipulated to excuse sin, not just the bad ones. We are even using grace as an excuse for licentiousness. Our hearts have been corrupted and our consciences dulled. Those other things are symptoms of the sin disease.
It sounds like even if this man is completely guilty, his church is willing to allow the grace and forgiveness of our God to be manipulated into a "we love sin" response. It will be dressed up in repentance and forgiveness, they will claim to "love the sinner and hate the sin," but it probably won't be the real deal. They will never get around to hating the sin enough to defend the righteousness of the standard. There are scriptural consequences like losing his leadership role that should happen if they really care about holiness and honoring Christ. If he is guilty of all the accusations, he was breaking civil laws right along with God's laws. Christians get so squishy and emotional about forgiveness that they lose all perspective on God's holiness and righteousness. If you love sin you do not love God.

That site has some problems itself as anyone who thinks their lives are squeaky clean.
Theology of Glory instead of the Cross? Perhaps.
