Let's acknowledge we have work to do
Politicians speak frequently of American exceptionalism and voice accolades describing America as the greatest country in the world. We ought to get away from that language for a while, as it conveys arrogance and indirectly disparages humility, a valuable trait that is often lacking and tempers arrogance with a dose of reality.
Our country has wrongs to right, perhaps two of the more notorious being the way we have treated black Americans and the original Americans (the American Indian) for centuries.
When we begin to truly and passionately attempt to right those wrongs, then perhaps we can again look at our country as Lincoln did: " ... a new nation, conceived in Liberty and dedicated to the proposition that all men (and women, emphasis added) are created equal." We have work to do.
