I'd like to add to your remark, that in addition, there is no lawful concept of the separation of church and state in the United States.
There is a "legal concept," but the enforcement is not lawful; that is, it is not Constitutional.
The First Amendment prohibits the government from establishing any religion as THE religion of the country and our government.
But the First Amendment does not prohibit our being a nation under God, nor does the First Amendment excoriate God from our country and our government.
The actual "separation" is with respect to power. Which is to say that the government is without any power to order what will be a person's religion under God. It is government that is "walled off" and limited.
Please note, that I said "under God." Because the definition of religion within the context of our Constitution, is with respect to God, in contrast to "belief systems" not about God.
Continuing, the government does not have the authority to separate God from our lives, nor does the government have the power to separate we and our religious beliefs from state property.
But therein lays one of the rubs, while exemplifying why we have the First Amendment "protection."
To commune and socialize without risk of religious "wars," to be frank, while on state property, i.e., the commons.
The First Amendment is instructive: Respect one another's religious inclination and maintain understanding and peace.
All these points were our framers' wisdom, calculated upon they and their forebearer's failure analysis over the centuries of previous governments which burdened and over-burdened men and women's lives and souls.
Welcome to America, where the country and government and Constitution respect your religion and your religious differences.
You might say that the First Amendment is the first civil rights act of the Constitution, long ago respecting peoples' differences. Indeed, the First Amendment gives notice, that you have the right to think and be different.
Within reason.
But most importantly, we should emphasize that the First Amendment, as is true for all the Bill of Rights, is primarily concerned with furthering the limits upon government, fencing in government, restricting again, what government can do, to what is on the list: enumeration of its authority.
The Constitution is a list of what government can do, binding it to only what is on the list, by reserving all other power to the people and to the states. It actually says that, right there in the Bill of Rights.
Would it be too much to ask, that high-school graduates and people applying to become legal immigrants, ought to be able to write out the Bill of Rights and explain their foundations?
Next time a "liberal" gives you grief, ask them what are the historical foundations for the First, Ninth, and Tenth Amendments.
And if said socialist is so upset at the "intolerance" of "diversity," and they cannot "get closure" about the "old dead white guys" who nearly all were the "Christian Right" who also made up the "vast right-wing conspiracy" against government tyranny ... then you'll hear that one is suppose to "embrace multi-culturalism" while eschewing individualism: Being an individual and owning property are bad.
Tell it on the mount.
Remember that I'll always be around.
