I see shifting patterns that don't point in one direction or another. For instance, there is a coarsening of popular culture, but church attendance is up across the country. These two phenoms are contradictory. I'm not implying they are related, but they are happening simultanously.
One piece of evidence which I can't believe you don't take seriously is the huge percentage of births to unwed mothers. Around one third of all births in the US are to unwed mothers, in the black community it's 75+% percent. Think about those numbers. In the UK it's 49%.
Social implosion due to the destruction of the family. Kids raised in what used to be called "broken homes" become very damaged, generally speaking. Of course, some overcome the damage. But many, many don't. Kids raised without their own mother and father in the home are at an extreme disadvantage, much higher incidences of drug/acohol use, molestation, violent behavior, acting out, promiscuity, and they have a much worse track record at being able to form stable marriages themselves.
If this doesn't herald danger to you, then you are either shutting your eyes willingly, or have extremely odd standards.
