"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." What tone is this excerpt?
