"The blood, sweat, tears, and suffering of Black people are the foundations of the wealth and power of the United States of America. We were forced to build America, and if forced to, we will tear it down. The immediate result of this destruction will be suffering and bloodshed. But the end result will be perpetual peace for all mankind."
