keep politics out of folk

That's as nonsensical as trying to argue that the personal isn't political.

My objection was to the unacceptable and preposterous tenet that people should go to festivals to wallow in a blinkered cocoon of laissez-faire complacency. Trad music chronicles the economic power struggles of the workplace as well as those pertaining to all social relationships, including the family. If exposure to the stories of those who have gone before fail to inspire you not necessarily how to place your vote (though it may have an influence) but to live your own life more humanely and strive for equality, I'd say you were missing the point entirely.
