This is one of these dumb issues were the solutions advocated are worse than the disease.
Yea nigger is rude out of any discriptive context even in Australia and NZ, I can remember my old man turfing out a few nephews over from NZ because they call Maoris savages. Its not that difficult to work out its not a form of punctuation.
Then theres the blowhards who offer solutions. The sort that will censor whites and not blacks creating more double standards, racism and resentment, plus theres the totolitarian aspect of language/thought controll which suggests if, and if its a big if, this could be achieved the types advocating it would move on to more mundane words, like democracy, rights etc. Which validates the missuse of the word.
Best to ignore it and hope it goes away, leave it to the black community to deal with their oafs. Its not going to drift into history when politicised.
