i tell people all the time, i believe that the most prolific thing ever written by king was his letter from the birmingham city jail. that letter dealt with all of the of the elements we were dealing with back then. people who said we were moving too fast. people said you re just wait. you remember that letter came was in response to a letter he received from eight white clergymen. who said to him that they thought his cause was right. but his timing was wrong chlgt. they asked him to leave birmingham because they said he was a disruptive force. well, king sat down to respond to them. didn t have any paper to write on. he used a margins of the newspapers to begin the answer.
