For instance, moronic expressions like "kick ass" are very prevalent in this culture.

I personally find that offensive, so you won't find me using the expression "kick ass" when there are any number of better ways to express the concept...

But what if a time comes when saying "kick ass" becomes officially deemed offensive, and is not politically acceptable in the media any longer? If so, there are going to be a lot of books and movies from the present to object to on that basis, aren't there? What will we do to protect society from such movies and books in the future? Dear, dear...!
