My problem is not that they can find justification out side the constitution, there are plenty of libs writing cr*p about the poor athesist who has to stand and be painfully offended with another leading a group prayer. How about just standing and RESPECTING another's belief? Same goes for the Salute to the Flag of the US. If for some reason you do not want to salute the flag -- and there are reasonable as well as tratorous reasons -- just stand there and be respectful. If you are not a christian, (I am Jewish) you should note that the nativity scene represents a holy time for another religion and be respectful of this.
We are headed in an insane direction by the initial supreme court decision establishing the separation of church and state doctrine and the court only has to look at the ten commandments decision to see just how conflicted and far from logic they have brought us.
