But you have to have hope. You have to be optimistic in order to continue to move forward.

If you see something that is not right, not fair, not just, you have a moral obligation to do something about it.

Nonviolence is one of those immutable principles that we cannot and must not deviate from.

I would like to think that we have made much more progress, that we've come much further, to have someone like a Donald Trump to emerge as the nominee of a major political party.

We have come a long way in America because of Martin Luther King, Jr. He led a disciplined, nonviolent revolution under the rule of law, a revolution of values, a revolution of ideas. We've come a long way, but we still have a distance to go before all of our citizens embrace the idea of a truly interracial democracy, what I like to call the Beloved Community, a nation at peace with itself.

Be prepared to organize nonviolent workshops - a teach-in around what is happening in America today. Organize your teachers and schoolmates, and be prepared to engage in some action.

I say from time to time that the vote is precious. It's almost sacred. It is the most powerful nonviolent tool or instrument that we have in a democratic society. And we must use it.
