"The loss of these wonderful people should make every one of us strive to be better. To be better in our private lives, to be better friends and neighbors and coworkers and parents. And if, as has been discussed in recent days, their death helps usher in more civility in our public discourse, let us remember it is not because a simple lack of civility caused this tragedy -- it did not -- but rather because only a more civil and honest public discourse can help us face up to the challenges of our nation in a way that would make them proud. . .
"We may not be able to stop all evil in the world, but I know that how we treat one another, that's entirely up to us. And I believe that for all our imperfections, we are full of decency and goodness, and that the forces that divide us are not as strong as those that unite us. That's what I believe, in part because that's what a child like Christina Taylor Green believed. . .
"Imagine -- imagine for a moment, 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 some day 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 and 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 to live up to her expectations. (Applause.) I want our democracy to be as good as Christina imagined it. . ."
