John Marshall Harlan said this quote
“ The sure guaranty of the peace and security of each race is the clear, distinct, unconditional recognition by our governments, national and state, of every right that inheres in civil freedom, and of the equality before the law of all citizens of the United States, without regard to race. State enactments regulating the enjoyment of civil rights upon the basis of race, and cunningly devised to defeat legitimate results of the war, under the pretense of recognizing equality of rights, can have no other result than to render permanent peace impossible, and to keep alive a conflict of races, the continuance of which must do harm to all concerned. ”
