From a report given by John Lewis to SNCC in 1965 (thanks to Ben Mabie)

"It matters not whether it is in Angola, Mozambique, Southwest Africa or Mississippi, Alabama, Goergia, and Harlem. The Struggle is one of the same. . Call it what you may - racial segregation, social, economic and political exploitation, or what the Freedom Fighters in South Africa are demanding an end to. . .imperialism and colonialism. It is a struggle against a vicious and evil system that is controlled nad kept in order for and by a few white men throughout the world."
