Let's take the thought a step further, for those who may be hearing (incorrectly) that I'm spouting atheism or anti-God views. This country was founded by people who were mostly Christians (of various and sometimes widely differing flavors) fleeing from religious persecution. The freedom to believe as they individually saw fit was one of the principal motivations for making the long and perilous trip to a strange, primitive, uncomfortable and sometimes savage new land. For almost all, it was a one-way trip -- a true leap of faith.
What they and many who followed helped to found was a nation that was, and is, firmly based on certain moral and spiritual beliefs - beliefs that are shared by almost all Religions if we dig down a little to the foundations of those various ways of believing. At the core of our moral and spritual foundations in America are the principles that virtually all Religions share at their heart. The only problem is that there have been and are individuals who desire to FORCE others or COERCE others into believing as they personally believe. The mullahs, the Taliban, the Inquisition, the Atheists and a few of our more garden variety faiths come to mind. Let's remember, however, that it's mostly not the belief system that drives this, but rather certain individuals who feel the need to dominate and dictate. Sure, many of our fellow men are enthusiastic about their way of belief and want to share it - even feel or are told by their Religious leaders that they have an obligation to "spread the word". That's perfectly OK in my book, as long as it's done with a respect for the privacy and rights of others and doesn't become an intrusive crusade that demands compliance on my part.
So, to be sure, America is a country based on certain definite spiritual and moral ideas and without those ideas we will not be the nation that our Founders envisioned. To the extent that we have lost or are losing those principles, our nation is threatened with a descent into the shadows of what we have been and can yet be. Let us fight against that and rally our fellow man to cherish and observe those ideas and to live them on a daily basis. As an individual, those ideas are at the heart and core of my spiritual and moral character even if I'm not always perfect in observing them. They remain my ideal and my ultimate measure and tourchstone of "right" behavior. Let us do unto others as we would have them do unto us and let us demand that others return the courtesy.
Our survival as free individuals may well depend on it.
