Well, Steve Roud (Folk Song in England) is pretty definite on the black face tradition deriving directly from the "n.. minstrels" of the early to mid 19th century, and gives a fair amount of evidence, so argue with him. And they don't ban black faces, only non- black faces blacked up. Which might make English dancing a bit more attractive to English people whose faces are naturally unwhite.

You can take the name "Folk England" other ways if you like, an Irish, Welsh or Scots nationalist might spell "folk" a different way. But the name EFDSS specifies dance and song, so tunes for their own sake and stories without tunes would seem to be marginalised.

And bugger nationalism, it buggers everything else up. Love of your own culture doesn't have to mean not-love of other cultures.
