You seem to feel your limited view/use of 'negro' is the sum total of views on the matter. You use the word to make a point about it being a poor word and Kelani is using the word "negroid" to make the point that a certain section of people are nameless as regards addressing color discrimination within African communities.

That was the original point.

So there is a qualified use of two aspects of the word by both of you. It is not like if she or you started off with the intention to call anyone a 'negro' although you degenerated to implying that she is a 'negro' by your definition of its ill meaning.

You can argue this point forever but as far as I am concerned she is within her right to qualify her use of the word to help address another pressing issue.
