`  == illustrations ==  I added a couple of pd pix, because there had long been a call for illustrations, and I thought these would lend a sense of historical usage. It would be good if we could find some modern ones, maybe images of racist grafitti? I remember that the ``Tom and Huck`` statue in Hannibal Missouri at the foot of Cardiff Hill used the word on an official plaque when I was a child (1930s-1960s) but was changed long ago. Wish I had a documentary photo.  This article illustrates better than any other I know the wikiprocess  a thorny, difficult, necessay topic with lots of disagreement, controversy, discussion, consensus and evolution  good job, people!  `
