I for one haven't been saying the pledge for 4 years, ever since I was old enough to understand the words and how many of them contradicted my own value system and morals. I've been reprimanded several times for not saying it, but nothing real has come of it yet.

The pledge was also used as an integral part of the plot of The Children's Story... (but not just for children) by James Clavell, (author of Shogun), to demonstrate how easily someone's beliefs can be manipulated.
I returned to school this year, now a big bad 10th grader. Today it is September 11th, 2002, that is, the first anniversary since the terrorist attacks. I haven't said the pledge for about two years, I reckon. When a teacher tells me to stand up, I do, otherwise I sit in silence while the pledge is recited.

Today our principal came on the loudspeaker and told us all to stand and say the pledge. I did it. I put my right hand over my heart and I said it, with my classmates, recited every word.

It felt so wrong. We may be guaranteed the right to not pledge, but that doesn't account for what people will say and think if you don't.
