I would suggest that it would be far less "embarrassing" to be seen as a Christian nation (Christianity being the power that defined Western civilization) than to be seen as Wiccans. Or as godless heathens, for that matter.
In any case, I don't know how advisable it is to make decisions for today based on the potential for "embarrassment" at some undetermined future date. I would further suggest that our cultural icons (e.g., our coinage) should rightfully reflect the values of the people they serve. And while I certainly appreciate the sensitivities of the vast Wiccan congregation in America, I believe our values are more accurately reflected in the phrase "In God We Trust" than "Kumbaya".
Unless those who dig us up are atheist or pagan, in which case we'll be seen as the quaint, backwards ancient society. Or maybe then they'll be into polytheism, and think we were weak because there was only one god.

I believe our values are more accurately reflected in "From many, one." That's the very definition of this country. We pull people from all countries and all religions to live here as Americans first and foremost. IGWT destroys that great concept.
