Yes. Remember when the highly combustible Leo Casey was on the list? He used the quote in his sig line, dragging it around everywhere like Marley's ghost with his chains:
Power concedes nothing without a demand. It never has, and it never will. If there is no struggle, there is no progress. Those who profess to favor freedom, and yet deprecate agitation are men who want crops without plowing the ground. They want rain without thunder and lightning. They want the ocean without the awful roar of its waters.
-- Frederick Douglass
