A serious question;
One thing that has often puzzled me: why is the word 'negro' classed as uncommon, while the (to me, anyway) much more offensive term 'nigger' is common?
I know that Chi's policy is to treat all taboo words, of whatever ilk, simply as words, so this is unlikely to have anything to do with being PC.
I can't imagine that either of these words is unfamiliar to any Chi player, so might I suggest that both words should be common?
