I am as yet unclear where the original poster sets out an assertion that his objection is to people (who I think may actually be Kurds) who are playing music and creating art that is not wholly Kurdish. There are two possibilities: one is that they are falsely representing that what they do is traditional, and if so then that falsehood deserves condemnation, but the other is that they make no false representation, in which case I can understand that they might wish to innovate in their art, and I would not condemn that as such.

It's very like "folk" or not. I don't necessarily dislike contemporary acoustic music, and indeed play some because I like it, but I don't call it "folk". On the other hand I may take a "folk" song, and arrange it: it's still a "folk" song but it is no longer wholly a "folk" song - compare Steeleye Span innovating in the presentation of folk.

What would be wrong would be to say that there must never be any change to music or art, or that everyone must like all types equally, or some not at all. Either of those things would be just as worthy of rebuttal as their analogues in other political arenas.
