What I find funny is, these people blame all the world's ills on sex and sexuality, but cannot provide one single study which backs up their position. Just blanket statements of "I find it wrong and shameful, therefore it is causing problems." Fact is, sexuality is as natural as breathing. It's a part of our very makeup. Denying sexuality is in it's entirety unnatural. There has never been any society that fell because people showed skin. Hell, look at many of the isolated tribes in the world whose societies haven't changed in hundreds, if not thousands of years; nudity of both sexes is common, their societies persisting, only threatened by outside forces.

Look at nudist colonies. You have adults and children all living quite nude. You don't see mass orgies or guys walking around with erections, and even sexual assaults are far rarer than in the outside world. Because it is all completely normal to those inside. Nudity is frankly banal when you are used to seeing it on a regular basis.

You want legitimate causes of problems in society? How about a lack of respect for education or the self, or any sense of personal responsibility? How about apathy, greed and solipsistic personalities, and others butting themselves into others lives while turning a blind eye on their own?
