I used to think that vulgar language had its place (and I guess I still do - old habits die hard)...for example, useful in emphasizing a strong point. As you know, I was brought up in a particular time and place where "bad words" were not to be spoken anywhere near females. This seemed to work quite well, as everyone pretty much conformed to this practise.
But, during the mid-late 60s, I noticed that it was becoming more acceptable to use these words in a public setting, no matter who might be present. I attribute that to the permissiveness that grew quickly during the "flower power" cultural change in Canada and the U.S. (the "hippy daze"). Interestingly, it seemed to me that one of the first "cultural bastions" to break down this language barrier was the hallowed halls of higher learning. The first time I heard a university professor utter the "F" word in a lecture, I almost fell off the chair.
Eventually, this language found its way into the movies and now we hear all kinds of bad words on television too. I hear it all the time on the street, from very young children...I am fond of calling it "mall rat language." It's a bit disappointing to a father to hear any young children expressing their disrespect of others, especially in such vulgar terms.
I guess the liberal types like to shrug their shoulders and say, "It's just the price of freedom." I disagree. I think it's an indication of a shifting value base - less respect for other people, complete disregard for the impact one's behaviour might have on others, and perhaps even a decrease in self-respect.
More extreme viewpoints say that it is leading to a general breakdown in society. There might be some truth to that, in that disrespect for others can easily become disrespect for law and order. Especially when the values begin to deterioriate...it can become hard to tell right from wrong.
Currently, freedom does seem to come with a price but I'm wondering if we're going to see a steady increase in the "Freedom Price Index." It could become costly for our entire society. In fact, we might be there already...we just have the costs buried well.
