Excerpt from i have a dream (2) martin luther king, jr. but there is something that i must say to my people who stand on the warm threshold which leads into the palace of justice. in the process of gaining our rightful place we must not be guilty of wrongful deeds. let us not seek to satisfy our thirst for freedom by drinking from the cup of bitterness and hatred. we must forever conduct our struggle on the high plane of dignity and discipline. we must not allow our creative protest to degenerate into physical violence. again and again we must rise to the majestic heights of meeting physical force with soul force. the marvelous new militancy which has engulfed the negro community must not lead us to distrust of all white people, for many of our white brothers, as evidenced by their presence here today, have come to realize that their destiny is tied up with our destiny and their freedom is inextricably bound to our freedom. we cannot walk alone. which statement uses the figure of speech of a metaphor? a) we cannot turn back. b) we cannot walk alone. c) we must not allow our creative protest to degenerate into physical violence. d) let us not seek to satisfy our thirst for freedom by drinking from the cup of bitterness and hatred.
