Some time ago, I read an article in Musical Traditions in which it was mentioned that some significant promoter of Black music in some part of the South was a member of the KKK. When someone asked for an explanation of this seeming paradox, someone with more knowledge of the South said that a person's membership in the KKK did not necessarily imply "hatred" of Blacks - but it meant that he wanted them "kept in their place".

Sorry for not being able to provide a little more detail - maybe some MT reader or writer can provide more ...
