yes!
"If there is no struggle, there is no progress. Those who profess to
favor freedom and yet deprecate agitation, are [those] 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,
and it may be both moral and physical, but it must be a struggle. Power
concedes nothing without a demand. It never did and it never will." --
Frederick Douglas
