An interesting article on the origin of the Pledge of Allegiance from the Cato Institute:

From its inception, in 1892, the Pledge has been a slavish ritual of devotion to the state, wholly inappropriate for a free people. It was written by Francis Bellamy, a Christian Socialist pushed out of his post as a Baptist minister for delivering pulpit-pounding sermons on such topics as “Jesus the Socialist.” Bellamy was devoted to the ideas of his more-famous cousin Edward Bellamy, author of the 1888 utopian novel Looking Backward. Looking Backward describes the future United States as a regimented worker’s paradise where everyone has equal incomes, and men are drafted into the country’s “industrial army” at the age of 21, serving in the jobs assigned them by the state.

And

Bellamy’s recommended ritual for honoring the flag had students all but goosestepping their way through the Pledge: “At a signal from the Principal the pupils, in ordered ranks, hands to the side, face the Flag. Another signal is given; every pupil gives the Flag the military salute–right hand lifted, palm downward, to a line with the forehead and close to it… At the words, ‘to my Flag,’ the right hand is extended gracefully, palm upward, towards the Flag, and remains in this gesture till the end of the affirmation; whereupon all hands immediately drop to the side.” After the rise of Nazism, this form of salute was thought to be in poor taste, to say the least, and replaced with today’s hand-on-heart gesture.

Crazy stuff…  It is a shame politicians have a history of reacting, instead of thinking.  Or researching.
