Obviously. Otherwise English folk songs and folk music are discriminated against, less learned, less studied, less performed and less propagated than many others.

But for some reason many will call it racist to say so.

I am not sure what criteria used to be applied at the sadly defunct National. I know there used to be an award for the best unaccompanied performance of a traditional folk song but I am not aware whether it was categorised by nationality or whether the traditional songs of England Ireland Scotland and Wales and/or other places were all equally eligible.
