"Those who profess to favor freedom, and yet depreciate agitation, are men [and women] who want crops without plowing up the ground. They want rain without thunder and lightning. They want the ocean without the awful roar of its many waters. This struggle may be a moral one; or it may be a physical one; or it may be both moral and physical; but it must be a struggle. Power concedes nothing without demand. It never did and it never will."
--Frederick Douglass, 1857
