If you download the entire membership list (see the link in the fourth posting) and then search it for "Folk" then you will find three other members - one who calls himself an activist - who give folk song amongst their "hobbies and interests". Mind you only a small minority of those listed actually state their "hobbies and interests".

Incidently, I don't think that this is a witch hunt. I don't give a damn about the star signs, shopping habits or football interests of other people, but when people who say they are interested in the music that I love and at the same time are members of a white supremist organisation, then I am interested in knowing who they are as I don't want the music that I love associated with such a cause.
