Clinton, your implication is that you can use such words with impunity if you are not bigoted.

I think not. In the context of our times, the use of such terms is the province of racists. And that's mnot necessarily the same as Jimmie Rodgers or Huck Finn using such words in the context of their times.

(Judging from your postings, I gather you think that "racist" is itself a bad word, but not the words of racists.)
