Nonviolent passive resistance is effective as long as your opposition adheres to the same rules as you do. But if peaceful protest is met with violence, its efficacy is at an end. For me, nonviolence was not a moral principle but a strategy; there is no moral goodness in using an ineffective weapon.

The Negro has many pent up resentments and latent frustrations, and he must release them. So let him march; let him make prayer pilgrimages to the city hall; let him go on freedom rides -and try to understand why he must do so. If his repressed emotions are not released in nonviolent ways, they will seek expression through violence; this is not a threat but a fact of history.

There is another way - a way as old as the insights of Jesus of Nazareth and as modern as the techniques of Mohandas K. Gandhi. For it is possible to stand up against an unjust system with all of your might, with all of your body, with all of your soul, and yet not stoop to hatred and violence.

So it means that we must rise up and protest courageously wherever we find segregation. Yes, we must do it nonviolently. We cannot afford to use violence in the struggle.

Urban riots must now be recognized as durable social phenomena. They may be deplored, but they are there and should be understood. Urban riots are a special form of violence. They are not insurrections. The rioters are not seeking to seize territory or to attain control of institutions. They are mainly intended to shock the white community. They are a distorted form of social protest.

As long as America postpones justice, we stand in the position of having these recurrences of violence and riots over and over again.
