This is a key tactic of the religious right--whining that their rights as Americans are being taken away. What rights? Freedom of religion? How does the government refraining from taking any position on religion infringe on anyone's rights? Quite the contrary, every time the government does take a position on religion, it is infringing on some people's sensibilities if not their rights.
For example, fundamentalists like to claim that atheism is a religion. That is bizarre and self-contradictory, but if we accept that as true, then any governmental recognition of God, no matter how non-denominational, is an act of disestablishment of the religion of atheism. Let me repeat: It is an act by which the government officially disestablishes a religion. Do any of those true believers want government to have the power to disestablish a religion? Or are they such hypocrites that they are okay with disestablishing "wrong" religions, as long as "right" religions are supported? Or, just maybe, is that claim, that atheism is a religion, utterly meaningless?
Some hard-core atheists want all of the common mentions of God eliminated from any governmental place or product, including inscriptions on coins and on governmental buildings. For better or worse, that is not going to happen, but it is interesting to note the basis of the courts' rulings on such cases to date: such routine mentions of God do not violate the First Amendment's establishment clause because they are not really religious messages, but cultural traditions. And the fundamentalists cheered their victory--yet their "victory" hinged on a ruling that rendered such mentions of God violations of the Bibilical commandment that we shall not take God's name in a vain and worthless manner.
Did they get that? Did they realize--or care--that their victory meant that the only way God's name could be mentioned was if it had no religious significance, if such mention was vain and worthless, if such mention is a violation of the commandment? No, they didn't care--they won the legal right to keep God's name worthless. And why should they care? They don't really believe in God except insofar as God is mentioned in the true object of their faith, the Bible. What they want is to turn America into a Christian nation, and claiming it always has been a Christian nation is the huge lie they tell over and over, to cover up the fact that they do not want to "restore" America but change it radically from what it has always been--a secular nation, most of whose citizens happen to be religious, and mostly Christian.
your use of the word fundamentalist here is way over broad; there are a few minority Re-constructionists that fit the general description-I '' quote you from above-

just substitute atheist with Re-constructionist and follow the the thought through by enforcing Biblical doctrine as law of the land-and end it with but that is not going to happen
there are hard-core radicals on both sides-they are both minorities-nether one is getting their way
the majority of those who state that "atheism is a religion" are using as a short-hand to describe the fervor of the aforementioned hard-core atheists
you are much more likely to have heard (especialliy in the 80's) that Secular humanism is a religion
and you kind of missed the main thrust of the 9th Circuit decision and followed down a valid by minor rabbit trail-its not so much that certain phrases are empty and meaningless as they are reflective of the State Civil Religion and are therefore exempt
