The ultimate test of a man is not where he stands in moments of comfort and movements of convenience, but where he stands in moments of challenge and moments of controversy
--Martin Luther King, Jr., January 27, 1965
Returning hate for hate multiplies hate, adding deeper darkness to a night already devoid of stars. Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that. Hate multiplies hate, violence multiplies violence, and toughness multiplies toughness in a descending spiral of destruction.
--Martin Luther King. Jr., "Loving Your Enemies," in Strength to Love
