Famous quotes containing the words king and/or frederick:
“I don’t think Dr. King helped racial harmony, I think he helped racial justice. What I profess to do is help the oppressed and if I cause a load of discomfort in the white community and the black community, that in my opinion means I’m being effective, because I’m not trying to make them comfortable. The job of an activist is to make people tense and cause social change.”
—Al, Reverend Sharpton (b. 1954)
“Up rose old Barbara Frietchie then,
Bowed with her fourscore years and ten;
Bravest of all in Frederick town,
She took up the flag the men hauled down;”
—John Greenleaf Whittier (1807–1892)
