“We didn't land on Plymouth Rock. The rock was landed on us.”
Speech at Founding Rally http://www.panafricanperspective.com/mxoaaufounding.html of the Organization of Afro-American Unity (28 June 1964)
Context: We are African, and we happened to be in America. We're not American. We are people who formerly were Africans who were kidnapped and brought to America. Our forefathers weren't the Pilgrims. We didn't land on Plymouth Rock. The rock was landed on us. We were brought here against our will. We were not brought here to be made citizens. We were not brought here to enjoy the constitutional gifts that they speak so beautifully about today.
