Just a bit of history. When Ike signed the bill adding "under God", he said: "From this day forward, the millions of our schoolchildren will daily proclaim in every city and town, every village and rural schoolhouse, the dedication of our nation and our people to the Almighty." So it's pretty clear that Congress and the Pres meant to establish a state sponsorship of religion.
Those who think that kids can just sit it out or omit the "under God" part should read this thread about what happens in the real world when you reveal your unchristianity:
