White Americans have different opinions about the word referred to by that common euphemism, "the n-word." Some ask why, if black people can use the actual word, white people can't; some don't see a problem with anyone using that word; some say no one should use it; and some (including me) say that white folks shouldn't use it, and that the question of whether black folks should use it is the business of no one else but black folks.
So it's clear that nearly all white Americans know what that euphemism, "the n-word," means. However, if you instead said another phrase to them, "the g-word," few would know which word you're referring to. That's mainly because in most situations, if someone catches a white person using the word that "the g-word" refers to, it's far less embarrassing for that person than if he or she had been caught using the word referred to by that other phrase, "the n-word." Since white folks think that their use of the actual "g-word" isn't all that embarrassing, they've seen no reason to create and use that euphemism ("the g-word") for it.
As with the actual "n-word," getting called out for using the actual "g-word" should provoke something worse than mere embarrassment for white folks. And that phrase, "the g-word," should become as much a part of the ordinary white American's vocabulary as the word that it refers to. And finally, of course, white usage of the actual word that it refers to should stop.
In this three-minute video, an author talks about his new book on this topic and, especially, about the repeated usage by one of our prominent politicians of the actual word that the phrase "the g-word" refers to.
