If everyone goes on saying the phrase "the N word" for long enough and not daring to actually voice or be confronted with the real word itself even when reading, for example, a historically signficant book like "Huckleberry Finn", presently people won't know what was meant by "the N word" any longer or what word WAS the "N" word...and then...someone might say it accidentally!!!!. This is a danger that I should think probably keeps a lot of people awake at night for hours. ;-) I mean, just imagine what could happen!
