Profanity

I was thinking recently, who made a word bad? What gives someone the right to make up a word and call it bad? It seems a little strange. We make words with letters which are little more than symbols in the American language. Who's to say that a combination of symbols is bad? And the sound we make. Who says that the sound we produce with our vocal cords is bad. "Bad words" really are nothing more than a farce. How come we have no good words that we cannot say? It seems strange. I can see how a word might develop with bad connotations to its meaning. We cannot say the word though? We cannot make the sound with our vocal cords? On the other hand, proper social etiquette indicates that the bad words cannot be said in public. That is just the way it is. Just like 2 plus 2 equals four, a word is a bad word. I am sure there are origins for the bad words, however. Profanities are words that are inappropriate and insulting to say but who made it that way? Should there be such as a bad word or good word that cannot be said? I would say a word here but, it is a bad one. There I said it.
