I think we could just agree that there are racial differences, and that my point was that the African American tradition shouldn't be rendered invisible by the Anglo American tradition.

I agree there was migration, adaptation, and assimilation into bluegrass and some country gospel on the Anglo side. My "stronger and more developed" is in reference to the music staying alive in the black church, more so than in white churches.

Hope that clears things up. I really don't think we are disagreeing about anything here.
