On the Left's view of the United States as a moral force on the world stage.
The United States has always been the moral force for freedom, and goodness and decency. Isn't that why so many of us just revolt at the view of this country held by the Left, and our current regime. They find our country flawed. They don't think we have any moral superiority when it comes to freedom and liberty, there is no such thing as this "beacon" business. They may say the words. Their policies don't follow it up.
