Here is a part of it:
Unfortunately, all too often when we talk about unity in this country, we've come to believe that it can be purchased on the cheap. We've come to believe that racial reconciliation can come easily - that it's just a matter of a few ignorant people trapped in the prejudices of the past, and that if the demagogues and those who exploit our racial divisions will simply go away, then all our problems would be solved.
All too often, we seek to ignore the profound institutional barriers that stand in the way of ensuring opportunity for all children, or decent jobs for all people, or health care for those who are sick. 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.
It's not easy to stand in somebody else's shoes. It's not easy to see past our differences. We've all encountered this in our own lives. But what makes it even more difficult is that we have a politics in this country that seeks to drive us apart - that puts up walls between us.
We are told that those who differ from us on a few things are different from us on all things; that our problems are the fault of those who don't think like us or look like us or come from where we do. The welfare queen is taking our tax money. The immigrant is taking our jobs. The believer condemns the non-believer as immoral, and the non-believer chides the believer as intolerant.
For most of this country's history, we in the African-American community have been at the receiving end of man's inhumanity to man. And all of us understand intimately the insidious role that race still sometimes plays - on the job, in the schools, in our health care system, and in our criminal justice system.
And yet, if we are honest with ourselves, we must admit that none of our hands are entirely clean. If we're honest with ourselves, we'll acknowledge that our own community has not always been true to King's vision of a beloved community.
We have scorned our gay brothers and sisters instead of embracing them. The scourge of anti-Semitism has, at times, revealed itself in our community. For too long, some of us have seen immigrants as competitors for jobs instead of companions in the fight for opportunity.
Every day, our politics fuels and exploits this kind of division across all races and regions; across gender and party. It is played out on television. It is sensationalized by the media. And last week, it even crept into the campaign for President, with charges and counter-charges that served to obscure the issues instead of illuminating the critical choices we face as a nation.
So let us say that on this day of all days, each of us carries with us the task of changing our hearts and minds. The division, the stereotypes, the scape-goating, the ease with which we blame our plight on others - all of this distracts us from the common challenges we face - war and poverty; injustice and inequality. We can no longer afford to build ourselves up by tearing someone else down. We can no longer afford to traffic in lies or fear or hate. It is the poison that we must purge from our politics; the wall that we must tear down before the hour grows too late.
