Also, I wonder what you mean with 'an agnostic nation', because you can't be 'an agnostic'. You're either an agnostic theist, or an agnostic atheist. Or so I recall...?
I mostly just meant a predominantly Agnostic country, but come to think of it, that wouldn't make it an Agnostic nation. You can't really have an Agnostic or Atheist nation. In my eyes, for a country to be identified with a religion, it needs religious laws (like certain middle eastern countries). Since Atheism and Agnosticism don't really have doctrines, you couldn't really make Atheist or Agnostic laws.
Actually the very moral fabric of our society as a christain nation is completley torn to shreds. Even Obama said he was christian its called a democratic republic, win over the voters. Every speech is written by a committee of hired professional writers so of course its going to be fanatic more like fantastical.
We are in 3 conflicts in the middle east and we still feel the sting of 9/11 Islam is this eras witch. During the 80's it was communists, during WW2 it was the Japanese.
We swear on the jefferson Bible after Thomas Jefferson not because it is God's holy scripture but because in truth it is Jeffersons version of God's Holy scripture.
We are only 200 years old we still have patriotism and traditions England is like centuries old and your traditions are still very strong and out of time.
We do not live in freedom from religion but freedom of religion anyone can believe anything they want. If you actually lived here and convened with people and have been seeing what has been going on latley America is completley turning its back on christianity and God altogether. The nativity scene was taken down infront of Washington D.C. and replaced with an athiest guidestone of their own ten commandments which didnt state any beliefs just what they dont believe. Bible have been strictly forbbidden in school since the 70's and now christianity is taught to be a myth. Christmas vacation is now winter break. America is sacrificing everything that ever remotley made us worth our spot on the Earth just to chase the Almighty dollar.
Im a christian and idc what anyone does or says honestly but take it from me America is not a christian country okay. Smoke and mirrors.
The influences on our country that come from christianity heavily outweigh everything you're talking about. I wish I could believe otherwise, but I can't.
