Azizi you have PM. I won't re-read what I posted on this thread because your interpretation of it may be, indeed is based on inferences within it, rather I'll explain what I intended to say, clearly inadequately.

The N-word and the sentiments behind it are designed to maintain an outsider group, those acting as shopkeeper and those beyond who can only admire the goods but are forever on the wrong side of the glass and intended to stay there. Folk music, depending on your point of view, is clearly not on the same level of discrimination. It is however, meant to be the indigenous musical expression of a people or sometimes a race. There are people who have hijacked folk-music for spurious nationalistic reasons and there are a second, and I believe much larger constituency, who have annexed the 'music of the people' and created an academic structure and a populist language intended to separate it from its creators and intended audience.

That separation relies on certain shibboleths - the 'folk' who made it are dead and anonymous without any 'claim' from contemporary 'ordinary people' who cannot continue its creation, delivering folk music into the hands of finer sensibilities who understand music unsullied by modernism. The comparison I made may be overwrought and of an entirely different order of magnitude but the underlying divisions are similar, to corral a once popular currency into a deserving minority who agree on its terms and conditions and create an underclass who disagree on those conditions, not through race or skin colour but through intellect and discernment.
