Joff-Rey!, the question of whether you should fight for your rights or go along depends on your reason, what it means to you, and how that balances with the consequences. Consequences include the effort to fight it (parent-teacher conferences, talking to the principle, maybe having to bring up the ACLU or whatever, causing a disturbance for all the other students, general loss of good-will from your teachers, etc). Since you didn’t state what your reason is, we can’t help evaluate that or provide more insight.
Unless I had a good reason, I’d probably stand out of respect to the teachers even if not actually participating. On the other hand, there can be good reasons not to. For instance, there was an incident in my high school (some years ago) where a group of students got in trouble for not standing for the flag at pep rallies. These students were Jehovah’s Witnesses, so it was a religious injunction. They were not being disruptive or rowdy, merely not participating. They got yelled at by the assistant principal and kicked out of the rally without justification. My sister joined in with them in protesting by not participating, on principle. It was eventually resolved - they were right.
It matters how disruptive you’re being, too. Quietly not participating is different than talking with a neighbor, making armpit noises, or throwing confetti, etc.
Turbo Dog, I will stand (or sit) quietly and not interrupt out of courtesy, but I don’t bow my head. Bowing the head is an act of participation, and I’m not participating. If anyone says anything to me about it, I’ll point out they had to look up at me to notice. They should worry more about what they were doing.
Your comment regarding money, some of us feel it doesn’t belong there, it’s there inappropriately. It was put there in the '50s out of fear of the “godless communists”. Some people would like to see it removed. I know people who scratch it out. But most of us ignore it, because it’s not what the money is about anyway. The money is just a symbol of value for trading purposes. What it says on it is irrelevant as long as it conveys that purpose. It could say “Try Anal Sex Today” and I’d still use it if that’s what constitutes money.
As for your comment about leaving the country, that’s stupid. Just because I don’t want to be forced to say the Pledge of Allegiance I should leave the country? Isn’t that what this country is about - freedom of conscience and freedom of expression? (By the way, I do say the pledge - minus the “under God” - and sing the anthem usually. I just do it as my choice, not as a requirement.)
