Are Martians attacking us or something?? I truly do not understand this statement.
The cultural values, norms and priorities of every society on earth reflect those who comprise that society. Those who pretend that all people are interchangeable do but project their hostility towards the realities of the human experience; their intolerance towards those who want to preserve their own legacies, etc..
As I wrote after the line you quoted:
Those Conservatives who are intimidated into silence by the hissing venom of indoctrinated Leftists, spraying the air as they call you "nativists," "racists," and "xenophobic," are a major part of the problem. We will either face this problem, now, or your grandchildren will have no place in the land of their forebears.
The unique qualities of America--as opposed to qualities that we really do have with many other peoples--reflect the unique nature of the early settlers, and their experiences in overcoming adversity, and building new societies from the ground up. These are reflected in their adversion to dependence on Government; in the understanding of the function of Government, as reflected in the Declaration of Independence, and in their respect for diversity--true diversity, not the degrading vision of the modern Left--where we have very different priorities and social values from State to State, while acknowledging what we also have in common, under the broad umbrella of the Constitution.
