Not really an argument, and as noted above I already do - but find it tricky as it's a moving target (not just those two words, but the greater field of word choice), and it's not as though there's a regular 'all hands' meeting for black people, women, Irish, Asians, short people, people who like coriander, etc where they decide collectively what the official position will be for their demographic.
As noted, I consider Reginald Hunter's opinion -- he thinks you, me, he, and everyone else should use the word a lot in order to remove / defuse its power.
Living in Australia there's a bunch of generally harmless words that are evidently quite powerful in the US. Always amusing to hear stories from friends travelling through the US who get hateful looks for using pussy, fanny, arse, and of course the c word, in casual conversation. But we (I speak for all Australians, naturally) don't think you (everyone else on the planet) needs to track our cultural foibles.
