Israel is surrounded by neighbors that have waged repeated wars against it. Israel’s citizens have been killed by rockets fired at their houses and s… - Barack Obama

Recall that earlier generations faced down fascism and communism not just with missiles and tanks, but with sturdy alliances and enduring convictions. They understood that our power alone cannot protect us, nor does it entitle us to do as we please. Instead, they knew that our power grows through its prudent use; our security emanates from the justness of our cause, the force of our example, the tempering qualities of humility and restraint.

The problem is that this kind of vilification and over-the-top rhetoric closes the door to the possibility of compromise. It undermines democratic deliberation. It prevents learning –- since, after all, why should we listen to a “fascist,” or a “socialist,” or a “right-wing nut,” or a left-wing nut”?

It makes it nearly impossible for people who have legitimate but bridgeable differences to sit down at the same table and hash things out. It robs us of a rational and serious debate, the one we need to have about the very real and very big challenges facing this nation. It coarsens our culture, and at its worst, it can send signals to the most extreme elements of our society that perhaps violence is a justifiable response.

So what do we do? As I found out after a year in the White House, changing this type of politics is not easy. And part of what civility requires is that we recall the simple lesson most of us learned from our parents: Treat others as you would like to be treated, with courtesy and respect. (Applause.) But civility in this age also requires something more than just asking if we can’t just all get along.

It is now our generation’s task to carry on what those pioneers began. For our journey is not complete until our wives, our mothers and daughters can earn a living equal to their efforts. Our journey is not complete until our gay brothers and sisters are treated like anyone else under the law for if we are truly created equal, then surely the love we commit to one another must be equal as well. Our journey is not complete until no citizen is forced to wait for hours to exercise the right to vote. Our journey is not complete until we find a better way to welcome the striving, hopeful immigrants who still see America as a land of opportunity until bright young students and engineers are enlisted in our workforce rather than expelled from our country. Our journey is not complete until all our children, from the streets of Detroit to the hills of Appalachia, to the quiet lanes of Newtown, know that they are cared for and cherished and always safe from harm.
