"Frankly, my dear ..."
But does it have to be that way? Lacing every sentence - whether spoken or written - with obscenities doesn't add much to the communication. If anything, it lowers the level of discourse. Why respect the views of someone who doesn't know how to effectively channel the power of words?
As for the blue language so often heard on TV or in movies, does art imitate life or does life imitate art? Back in the pre-TV days, film viewers were absorbed by the power of love and hate without bedroom scenes and forbidden words. That's why Clark Gable's "Frankly, my dear, I don't give a damn'' became an iconic movie line.
Times may have changed, but I suspect there are many people today - of all ages - who would rather think about words than be bludgeoned by them. And that's not being priggish.
