"There is not a nation on the earth guilty of practices, more shocking and bloody, than are the people of these United States, at this very hour. 

Go where you may, search where you will, roam through all the monarchies and despotisms of the old world, travel through South America, search out every abuse, and when you have found the last, lay your facts by the side of the everyday practices of this nation, and you will say with me, that, for revolting barbarity and shameless hypocrisy, America reigns without a rival."

Fredrick Douglass, 1852, What to the Slave is the Fourth of July?
