Why does that upset some people so?

Doesn't upset anyone, John P - least of all me - it's just more theological bullshit to wade through. As I say - all music is born of tradition, therefore all music is traditional. Sorry for not answering your earlier questions, but puerile stuff like Huh? Who purports anything about any tradition? doesn't inspire me to respond one way or the other.

Otherwise, Folk is not a music, it is a parasitic conceptual agenda looking for a music to attach itself too; that it chose the traditional music and song of the working class is largely because they couldn't answer back as their masters and betters took such an unprecedented interest in their culture and subjected it to the sort of taxonomical hysteria which typifies the folk enthusiast right up to our present time. It's an odd sort of legacy to be sure, but the parasitical agendas of The Folk Revival no more accounts for the traditional music and song of the English working-class than defining that class as The Proletariat accounts for their role in the fantasy class-struggle as postulated by Karl Marx.
