A very good description of the two, in relation to the claim that our president doesn’t love America, from the Acton Blog.

An excerpt.

Last week former New York City mayor Rudy Giuliani set off a firestorm of debate and criticism by openly questioning1 whether President Obama “loves America.”

“I do not believe, and I know this is a horrible thing to say, but I do not believe that the president loves America. He doesn’t love you. And he doesn’t love me. He wasn’t brought up the way you were brought up and I was brought up through love of this country.”

It would be easy to completely dismiss Giuliani’s comments as dumb, uncharitable, and partisan because the comment was dumb, uncharitable, and partisan. But I believe the mayor has an intuitive sense about something that he can’t articulate, and probably doesn’t understand.

The reality is that Obama and Giuliani both love America. Obama and Giuliani are both patriots. Yet their idea of what love of country means and what patriotism requires of them are likely to be significantly different. To understand this difference let’s look back to a comment from 2007.

As candidate for president in 2007, Barack Obama was questioned about why he did not wear a flag pin on his lapel. His explanation was that he had done so once but he believed it had become a substitute for “true patriotism” since the Sept. 11, 2001 terrorist attacks.

“You know, the truth is that right after 9/11, I had a pin. Shortly after 9/11, particularly because as we’re talking about the Iraq war, that became a substitute for I think true patriotism, which is speaking out on issues that are of importance to our national security, I decided I won’t wear that pin on my chest.”

Obama wasn’t just saying the pins had become a cliché; he was saying he no longer wore the pins because they are no longer—at least for him—authentic symbols of patriotism. In other words, the reason Obama was refusing to wear the pin on his chest was not that he wasn’t patriotic, but because he was “post-authentic.”

This does not mean, of course, that Obama does not have an authentic love for his country or that his patriotism is not authentic. Post-authentic means something quite different.
