Words and No Words

Sometimes I wonder if we decrease the value of words. It seems of late people throw around words and phrases like "fuck" and "shit" and "I love you" and "I hate you". As a result the language loses its value as an element meant to convey serious and/or deep emotions due to over usage. Why does no one see this? Can we stop this? Because when I fall in love I want it to have meaning. And when I want to insult someone, it would be nice if that had meaning too.
