Alternatively, WLD, we could recognise that what makes folk music folk music is the tradition (yes, new music can enter the tradition, but by osmosis and adaptation), and that what you want is apparently something else. If you want a country music club, or a line dancing club, or a place where fretwankers can show off (presumably they don't give a stuff what anyone else is doing, they just want to turn it up to 11 and widdle), go have one. Just don't break the trade descriptions act by calling it anything to do with folk.

You could call it an "Olk" club (there is no f'in folk).

Or you could take folk and arrange it or add to it or find other ways to bring out its hope, its anger, the dark side of human life that it records and illuminates. If you forget who you were, you know not fully who you are, and in a way that lessens you as a person - this is not a personal insult, we have enjoyed many an amiable row, but it is so strange that while so many whose predecessors came from Africa, India, and the near East (it doesn't seem to happen so much as far as I know for the far East) are fervently exploring and re-affirming their "roots", so many whose predecessors were European are busily rejecting theirs.

OK, maybe I have a bee in my bonnet about it, but, as you said (or was it someone else?) when you see someone promulgating the views that have destroyed (or are destroying) something of value to you there is a great need to try to correct them.
