"And so we can preserve great traditions -- music, food, dance, language, art -- but if there’s a tradition anywhere in Africa, or here in the United States, or anywhere in the world that involves treating people differently because you’re scared of them, or because you're ignorant about them, or because you want to feel superior to them, it's a bad tradition. And you have to challenge it. And you can't accept excuses for it. But the truth of the matter is, is that if you’re treating people differently just because of who they love and who they are, then there’s a connection between that mindset and the mindset that led to racism, and the mindset that leads to ethnic conflict. It means that you’re not able to see somebody else as a human being. And so you can’t, on the one hand, complain when somebody else does that to you, and then you’re doing it to somebody else. You can’t do it. There’s got to be some consistency to how you think about these issues. And that’s going to be up to young people -- because old people get stuck in their ways. And that doesn’t mean that everything suddenly is perfect. It just means that, young people, you can lead the way and set a good example. But it requires some courage, because the old thinking, people will push back at you. And if you don’t have the convictions and the courage to be able to stand up for what you think is right, then cruelty will perpetuate itself."

““In giving freedom to the slave, we assure freedom to the free.” That’s what President Lincoln once wrote. “Honorable alike in what we give, and what we preserve. We shall nobly save, or meanly lose, the last best hope of earth.” Mr. Speaker, leaders and members of both parties, distinguished guests: We gather here to commemorate a century and a half of freedom -- not simply for former slaves, but for all of us. Today, the issue of chattel slavery seems so simple, so obvious -- it is wrong in every sense. Stealing men, women, and children from their homelands. Tearing husband from wife, parent from child; stripped and sold to the highest bidder; shackled in chains and bloodied with the whip. It’s antithetical not only to our conception of human rights and dignity, but to our conception of ourselves -- a people founded on the premise that all are created equal.”

“Ramadan is a celebration of a faith known for great diversity and racial equality.”

“Above all, when your voices are heard in government, it's far more likely that your basic needs will be met. And that’s why reform must reach the daily lives of those who are hungry and those who are ill, and those who live without electricity or water.”

“In the end, that's what this election is about. Do we participate in a politics of cynicism or a politics of hope? I'm not talking about blind optimism here... No, I'm talking about something more substantial. It's the hope of slaves sitting around a fire singing freedom songs; the hope of immigrants setting out for distant shores; the hope of a young naval lieutenant bravely patrolling the Mekong Delta; the hope of a millworker's son who dares to defy the odds; the hope of a skinny kid with a funny name who believes that America has a place for him, too. Hope in the face of difficulty, hope in the face of uncertainty, the audacity of hope: In the end, that is God's greatest gift to us, the bedrock of this nation, a belief in things not seen, a belief that there are better days ahead.”

“Every nation struggles to define citizenship. America has had great debates about these issues, and those debates continue to this day, because we’re a nation of immigrants -- people coming from every different part of the world. But what we’ve learned in the United States is that there are certain principles that are universal, apply to everybody no matter what you look like, no matter where you come from, no matter what religion you practice. The right of people to live without the threat that their families may be harmed or their homes may be burned simply because of who they are or where they come from. Only the people of this country ultimately can define your union, can define what it means to be a citizen of this country. But I have confidence that as you do that you can draw on this diversity as a strength and not a weakness. Your country will be stronger because of many different cultures, but you have to seize that opportunity. You have to recognize that strength.”

“Citizenship demands a sense of common purpose; participation in the hard work of self-government; an obligation to serve to our communities.”
