While I'm not 100% on this, I believe that the ceremony of the peace-pipe was used as a "binding" element for antagonistic tribes who were planning to raid or go to war with one another, not to do so.<quoted text>Can Muslim kids whip out a prayer rug at noon, as a group, in an American public school, or is it banned?
Can native American kids pass a peace pipe, do a rain dance, or perform coming of age rituals, as a group, in an American public school, or is it banned?

When one approaches freedom of/from religion, in the context of the Constitution of the United States, one has to take ALL CITIZENS into consideration.
When one approaches religious freedom from the standpoint of religious persecution, one would be wise to consider one's own GUILT AND SHAME on that score, Christian.
In that context, it's kind of hard to imagine kids--unless they happen to be members of rival gangs--going through the ritual of smoking a peace-pipe.
That said, I completely agree with the rest of your post; I find myself gnashing my teeth whenever someone says, "It's Freedom OF RELIGION, not FREEDOM FROM RELIGION."
What those folks don't seem to comprehend is that that statement is tantamount to saying that only "religious" people are worthy of freedom. If you're not religious...tough tookies for you.
