Second, more measured response, to clearblue's links:
Alinski's Rules for Radicals are cheap, low down, guidelines for making sure you get your point of view across and cause change for the worse to make better opportunities for your side to get what it is told that it wants.
Generalist Social Workers, Community Organizers, and Labor Leaders all have far more experience and rules to reference, including vast bibliographic resources. And they work within the rules for the most part. Alinski is, however valuable to read so you know your enemy.
Folk singers are also part of the history of the labor and civil rights movement, spreading an oral history with their songs. Which is why the folk group The Weavers was the only musical group to be blacklisted during the McCarthy Red Scare. Consider these lyrics by Woody Guthrie:
"They asked would I fight for my Country?
I answereed the FBI 'Yea',
I will point a gun for my country,
But I ain't guaranteeing which way."
