I say that anyone claiming to have been called a racist for liking english music is in fact a liar.
If I am wrong then the person accusing racism must be a lone idiot, so why would anyone bother to mention it...
...but to propagate the BNP lie that "White" traditions are under some sort of sustained onslaught.
On the blackface issue, I don't know anyone who would actually be offended by it (my recently ex-partner, still close friend, of 7 years is of Pakistani origin and I am a committed anti-racist / anti-fascist activist with a lot of supremely 'PC' friends and colleagues). I think the school over-reacted.
However, there is "always one", as the saying goes, and probably the same imaginary "one" that says liking trad music is racist.
Folk traditions are not pickled in aspic, they constantly evolve. Once there were no blackface morris-men. Then, for social reasons of some sort, they wanted to disguise themselves and used what was to hand...burnt corks.
Now, if it is claimed that society might now not appreciate blackface, why not just choose a different coloured disguise (as many sides have done) It is the disguise that is the essence of the tradition, not the colour.
