“Respect for the God-given dignity of every human being, no matter their race, ethnicity or other circumstances of their birth, is the essence of American patriotism. To believe otherwise is to oppose the very idea of America.”

Context: Every one of us is equal. Every one of us has worth. Every one of us matters. And when we respect the freedom of others -- no matter the color of their skin, or how they pray or who they are or who they love -- we are all more free. Your dignity depends on my dignity, and my dignity depends on yours. Imagine if everyone had that spirit in their hearts. Imagine if governments operated that way. Just imagine what the world could look like -- the future that we could bequeath these young people.

2014, Sixth State of the Union Address (January 2014)
Context: And finally, let's remember that our leadership is defined not just by our defense against threats but by the enormous opportunities to do good and promote understanding around the globe, to forge greater cooperation, to expand new markets, to free people from fear and want. And no one is better positioned to take advantage of those opportunities than America. Our alliance with Europe remains the strongest the world has ever known. From Tunisia to Burma, we're supporting those who are willing to do the hard work of building democracy. In Ukraine, we stand for the principle that all people have the right to express themselves freely and peacefully and to have a say in their country's future. [... ] We do these things because they help promote our long-term security. And we do them because we believe in the inherent dignity and equality of every human being, regardless of race or religion, creed or sexual orientation. [... ] My fellow Americans, no other country in the world does what we do. On every issue, the world turns to us, not simply because of the size of our economy or our military might but because of the ideals we stand for and the burdens we bear to advance them.
