I must respond to a recent anti-American tirade with a few questions. When strong moral leadership is mentioned, I ask, “Whose morality?” When a rededication to God is mentioned, I ask “Whose God?” When family or community is mentioned, I ask “Whose family? Whose community?” If you answer any of those questions with “mine,” then you are advocating the same kind of fundamentalist tunnel vision practiced by the people who consider America to be Satan.
As for the reasons for the downfall of the Roman Empire (which may not be the best analogy, as the Romans forced their culture on anyone they could brutally conquer), there are some who consider the rising power of Christianity as the final nail in the Empire's coffin.
Is it possible a natural backlash for the forced “melting pot” (a Jewish man coined that phrase, by the way) policies contribituted to a more liberal and multicultural landscape? Perhaps there are some Indians who would love to discuss the phrase “assimilation” with you. Ask a few who were sent to the boarding schools from the reservation.
I am sorry for those who have such a depressing, gloomy vision of life in the United States. I personally do not live in a “over-indulgent, self-deprecating, immoral, cesspool of depravity.” If I did feel that way, I might consider listening to those who say “America, love it or leave it.”
As a gifted young man once said “... do what you want to us, but we won't sit here and listen to you bad-mouth the United States of America! (whistling the National Anthem in the background).”
