Re-read my point. You've obviously missed it.
I'm not sure you get it either. Paul, God's apostle, tells us that a church should not be a gathering place for grossly unrepentant sinners. If parents were attempting to raise their children according to a biblical standard and fornicators among the youth group were not disfellowshiped, it's a blatant, heretical invitation to sin. As I said, if you have a problem with that, take it up with God's word.
