"So I'm a Marxist now to add to my faults?"

I've no idea and wouldn't count it a fault anyway. I just noticed a similarity between "folk song collecting, scholarship, and attempts at revival (are) malign forms of appropriation and exploitation by the bourgeoisie of the working class" (wikipedia pp Harker), and "the middle classes nicked the tradition" (glueman) - not to mention sarcastic remarks about "noble savages" and "the great unwashed".
