You've seen the video & maybe had a good snicker over it. But consider: These people aren't forcing their morals on anyone--and when have liberal entertainment industry types ever been shy about forcing their *lack* of morals on everyone else?
Amazingly enough, to some, there are people in the world who don't want to be sybarites, libertines, spiritual and moral slobs. They long for a zone of purity and cleanliness around themselves. They understand, however inchoately, that when anything goes, nothing matters. They don't want their own God-given sexualities not to matter. Clean living under adverse cultural circumstances is an achievement which deserves praise, not derision.
