As a student of history, I also know civilization's debt to Islam. - Barack Obama

I believe in the principle of treating people equally under the law, and that they are deserving of equal protection under the law and that the state should not discriminate against people based on their sexual orientation. And I say that, recognizing that there may be people who have different religious or cultural beliefs. But the issue is how does the state operate relative to people. If you look at the history of countries around the world, when you start treating people differently -- not because of any harm they’re doing anybody, but because they’re different -- that’s the path whereby freedoms begin to erode and bad things happen. And when a government gets in the habit of treating people differently, those habits can spread. And as an African-American in the United States, I am painfully aware of the history of what happens when people are treated differently, under the law, and there were all sorts of rationalizations that were provided by the power structure for decades in the United States for segregation and Jim Crow and slavery, and they were wrong.

For peace to come, it is time for them - and all of us - to live up to our responsibilities.

That's what I believe, in part because that's what a child like Christina Taylor Green believed. Imagine: here was a young girl who was just becoming aware of our democracy; just beginning to understand the obligations of citizenship; just starting to glimpse the fact that someday she too might play a part in shaping her nation's future. She had been elected to her student council; she saw public service as something exciting, something hopeful. She was off to meet her congresswoman, someone she was sure was good and important and might be a role model. She saw all this through the eyes of a child, undimmed by the cynicism or vitriol that we adults all too often just take for granted. I want us to live up to her expectations. I want our democracy to be as good as she imagined it. All of us — we should do everything we can to make sure this country lives up to our children's expectations.
