From Martin Luther King, Jr.’s “Letter from a Birmingham Jail“:

I must confess that over the past few years I have been gravely disappointed with the white moderate … who prefers a negative peace which is the absence of tension to a positive peace which is the presence of justice … Shallow understanding from people of good will is more frustrating than absolute misunderstanding from people of ill will. Lukewarm acceptance is much more bewildering than outright rejection.
