"ethnic" has always been another name for "traditional" in relation to music and other aspects of a culture, such as clothes or food, since long before people got this strange notion that the word should only be used in the context of some ethnic groups and not others.

All the traditions deserve to be encouraged and supported. The ones which are more at risk deserve particular attention, and in England that includes traditions that are linked historically with minorities within the majority ethnic groups.

Multiculturaism is a great idea - but it needs to include all the cultures.
