You Do Not Have to Say the Pledge of Allegiance
The Supreme Court of the United States ruled in West Virginia State Board of Education v. Barnette, 319 U.S. 624 (1943) that it is unconstitutional, on principles of freedom of religion, freedom of speech, due process, and equal protection, to compel anyone to salute the American Flag or to recite the Pledge of Allegiance.
When I was in high school (I'm in my twenties) in Texas, the general belief was that students were required to stand, salute, and recite the Pledge of Allegiance. When challenged, staff would refer to "state law", by which they meant the Texas Education Code. This and any similar things in other states are, of course, superceded by the SCOTUS ruling. The section linked was added in 1995 and amended in 2003, despite a conflicting, trumping decision from long before.
I've been putting off writing something for this for several years. Now that I've finally gotten around to it, it came out nicely. I don't know if anyone's a student here or if it's just the same group of [former] kidiots, but I figured TOTSE would like it, anyway.
