Regarding fate of a politicized musical tradition when the opposite side takes over.

Consider the recent debates in regard to torture.

The most important most often cited case against torture has been the assumption that the reason the good people don't torture is because they do not wish to have torture visited upon them when the good guys are captured.

Same for folk music. When the tide changes you loose if you are overly one sided- branded.

Actually with Regan and the rise of consevative points of view this is exactly what happened to folk music. It lost its issues. Civil Rights and the war and then being branded lefty-hippie it was not selected by the people who made the choices when the culture changed.
This would not have happened had a wider variety of views been presented.

Each time we loose a song we loose a treasure no matter what the song is about.
