This story is actually just the recent manifestation of an old debate. 
http://www.thesmokinggun.com/archive...28101rap1.html  (White man beaten because "white people shouldn't be listening to rap")  The debate is whether certain forms of cultural expression belong to certain cultures.  In particular: can a non-Jamaican produce "authentic" reggae music?  Can a Russian woman produce "real" Vedic music?  Or how about an Inuit engaging in "meaningful" tibetan throat songs?
Who OWNS culture?  Is there such a thing as AUTHENTIC culture?  Was Ralph Ellison right when he bashed the whole idea of "
cultural authenticity"?
