////When it comes to folk music, most American folk music has British Island roots. I think a whole army of American folklorists would say that strongly in chorus.////

If you're so Eurocentric in your views that the only American folk music that matters is white people's, if you can so blatantly ignore the huge contributions of Latins, Indians, and blacks that you even think Django Reinhardt invented jazz, it is you who is chauvinistic and probably a racist as well.
