Considering the country was based upon the religious values of it's founders, I don't see much of a problem with it...
Which founding father are you talking about, the atheist, the diest, or the sarcastic philanderer?
And seeing that taken together these various insurgents and slaveholders created a document that explicitly demanded the separation of church and state, I fail to see where this myth of these "christian values of our forefathers" has emerged from, other than the cesspit of the News corporation.
It is my firmly held belief that the only way that the united states, and each and every public servant within it, should work with religion is to ensure that each and every faith, creed, and philosophy is allowed to flourish to the fullest extent that does not interfere with the inalienable rights of others.
The description of these rights is a vague and dangerous thing; it in and of itself skirts the territory of philosophy and religion. I think it is not, however, impossible to create a simple system of rules that allows for these freedoms. At the very least, we know that the freedom to live life must exist, and so a religion built around human sacrifice- or, at least,
unwilling human sacrifice- would violate those rights, and it would be within the duty of government to stop it.
If however (to pick a topic at random), a cult existed centering around the harvesting and consumption of hypnotic fungi, and this material proved not to have harmful effects that where not known to the users or other long-term effects, then the government would be powerless to stop it.
As a practical application of this, it is the privilege of a church, temple, synagogue, etc.,to teach followers, not the duty of government provided schools.
