Dr. King understood that peace without justice was no peace at all; that aligning our reality with our ideals often requires the speaking of uncomfortable truths and the creative tension of non-violent protest. But he also understood that to bring about true and lasting change, there must be the possibility of reconciliation; that any social movement has to channel this tension through the spirit of love and mutuality. If he were alive today, I believe he would remind us that the unemployed worker can rightly challenge the excesses of Wall Street without demonizing all who work there; that the businessman can enter tough negotiations with his company’s union without vilifying the right to collectively bargain. He would want us to know we can argue fiercely about the proper size and role of government without questioning each other’s love for this country -- (applause) -- with the knowledge that in this democracy, government is no distant object but is rather an expression of our common commitments to one another. He would call on us to assume the best in each other rather than the worst, and challenge one another in ways that ultimately heal rather than wound.

We long for unity, but are unwilling to pay the price. But of course, true unity cannot be so easily won. It starts with a change in attitudes - a broadening of our minds, and a broadening of our hearts.

Now, there’s no easy answer for resolving all these social forces, and we must respect the meaning that people draw from their own traditions -- from their religion, from their ethnicity, from their sense of nationhood. But I do not believe progress is possible if our desire to preserve our identities gives way to an impulse to dehumanize or dominate another group. If our religion leads us to persecute those of another faith, if we jail or beat people who are gay, if our traditions lead us to prevent girls from going to school, if we discriminate on the basis of race or tribe or ethnicity, then the fragile bonds of civilization will fray. The world is too small, we are too packed together, for us to be able to resort to those old ways of thinking.
