Martin Luther King, Jr. - Wikipedia, The Free Encyclopedia

https://en.wikipedia.org/wiki/Martin_Luther_King,_Jr.:  King was arrested and jailed early in the campaign—his 13th arrest[111] out of 29.[112] From his cell, he composed the now-famous Letter from Birmingham Jail which responds to calls on the movement to pursue legal channels for social change. King argues that the crisis of racism is too urgent, and the current system too entrenched: "We know through painful experience that freedom is never voluntarily given by the oppressor; it must be demanded by the oppressed."[113] He points out that the Boston Tea Party, a celebrated act of rebellion in the American colonies, was illegal civil disobedience, and that, conversely, "everything Adolf Hitler did in Germany was 'legal'".[113] King also expresses his frustration with white moderates and clergymen too timid to oppose an unjust system:

I have almost reached the regrettable conclusion that the Negro's great stumbling block in his stride toward freedom is not the White Citizen's Councilor or the Ku Klux Klanner, but the white moderate, who is more devoted to "order" than to justice; who prefers a negative peace which is the absence of tension to a positive peace which is the presence of justice; who constantly says: "I agree with you in the goal you seek, but I cannot agree with your methods of direct action"; who paternalistic-ally believes he can set the timetable for another man's freedom; who lives by a mythical concept of time and who constantly advises the Negro to wait for a "more convenient season".
