I would not pledge allegiance to the symbol of a (hypothetical) dictatorship which told me what I could not do, no matter how pious the dictator might be. I will say the Pledge, and be proud of doing so, because I do believe in God, and because the flag is the symbol of a free country, in which citizens are guaranteed the freedom to believe as they choose. My great-great-great-great-grandfather fought to free this country from the rule of an English king with an established religion (ironically, the ancestor of the church in which I hold membership!).
Part of that freedom is enshrined in the First Amendment to the Constitution. This addresses religion in two ways (as I have detailed over in the Liberal Christianity forum on this board): the right to freely exercise ones religion, without government interference, and the right to be free from government compelling or coercing you to profess allegiance to a system of beliefs (i.e., a religion) that it establishes. It also protects ones freedom of speech, to be able to say or not say what is on your mind, with government interference limited to very explicit abuses (e.g., advocacy of armed rebellion against the U.S., child pornography, the provision of a government-sponsored public forum for hate speech).
The original statute adopted by Congress which adopted the Pledge of Allegiance, and the 1954 amendment, simply set forth the text as the proper way in which an American may pledge allegiance to the country, by addressing his/her pledge to the flag as its symbol. It is not and cannot be unconstitutional, because it is not a requirement on anybody as a citizen.
According to a Supreme Court case that has been good law for 62 years, West Virginia State Board of Education v. Barnette, it is unconstitutional to compel anyone to recite the Pledge. Later cases have extended that prohibition to coercion by the example of a government authority or by peer pressure. You cannot say, for example, All patriotic Americans will now stand and recite the Pledge of Allegiance. But you can remain seated, or stand silently, if you so choose. Thats coercion at its worst.
In the Newdow case now up for Supreme Court consideration, the Ninth Circuit Court held two very interesting positions: (1) That the requirement in a school boards regulation that the Pledge be recited every morning in every class in its school district constituted an establishment of religion, because the God whom the Pledge asserts that were one nation under is the Judaeo-Christian God (and does anybody in this debate question that? Does anybody think that its really Brahma, or Zeus, or Odin being referred to?). As such, its a violation of the First and Fourteenth Amendments. [The First Amendment only restricts Congress and the Federal government; the Fourteenth says that the freedoms guaranteed by the Constitution cannot be abridged by the States (or the local governments, including school boards, which they create) either.] And (2) the Ninth Circuit was explicit that what it was ruling unconstitutional was the school board regulation, not the Pledge itself, and that it explicitly refused to rule on Newdows contention that the Pledge was unconstitutional.
Im proud to say the Pledge, because I love the free country in which I was blessed to be born and live. I have never been prouder of my grandkids than the day I took them to the State Museum, and as we walked past the flag flying in front of the State Legislature Building a block away, they turned and spontaneously recited the Pledge together.
But for anyone to require by law that people must recite it, is a violation of the very principles on which it was founded, the free constitutional republic for which the Flag stands. And that deserves combating.
Recite the Pledge; teach your children the Pledge. Teach them to be proud of this country, and of the freedom that we have and that its worth guarding, with your life if necessary. But dont try to take away any piece of that freedom in an effort to force others to think as you do. Thats what happened to the Russian Republic before it even got off the ground, back in 1917; thats what happened to the German Republic in 1933.
The old line from Vietnam, We had to destroy the village in order to save it, comes to mind. Dont destroy freedom in the name of honoring it.
