Institutional atheism? Let me try to say it louder: WE ARE NOT ASKING FOR THE WORD "GODLESS" TO BE INSERTED INTO THE PLEDGE OF ALLEGIANCE. Now, THAT would be institutionalizing atheism in government schools. But, by including the words "under God", which were not in the original version, you are institutionalizing religion.
Te philosopher JP Sartre said the everyone must choose between belief/nonbelief, not choosing is also a choice that equates to nonbelief. Likewise, we as a nation must choose whether we are a godless nation or a god-filled nation.
The attempt by Dips to say that they are somehow "above" religion and are therefore an impartial arbiter is absurd. They bring as much faith to the fight as any radical Islamist.
