Wow, Larry, thats a great article. Great specifics which were carefully avoided by the standards.Just as an overview argument, American Exceptionalism is, IMHO, merely the fact that the American Great Experiment was - an experiment. It had to deliver the blessings of liberty or be a failure. To say that America is not exceptional is to say that it is a failure.
But to say that America is a failure flies in the face of the historic American Immigration phenomenon. People do leave America - but people want to come. Yes, land ownership is more available here - in places. But even that is an artifact of the domestic tranquility established here. And yet we see anti conservative activism subverting tranquility, a government working against its own authority.
