I have a hard time understanding it, though I know it is wrong to say the word as a Caucasian. I am a Jew and I would never call another Jew the K word or any other word that is used as a slur against Jews. I don't know that other ethnicities do call each other slurs. I think the N word is an ugly word as are all racial/ethnic slurs. I don't understand how you take the power from those that used the word originally by using it yourself. Honestly, I hate hearing it over and over again in songs and in songs where they only say it once or twice, I have accidentally said it myself why singing the lyrics. I then chastise myself for letting it slip out, but when you are singing along to a song, you are not really thinking about what your are saying.
