The school handbook, approved by the Board of Education, states the children must stand for the Pledge but they don’t have to recite it.
That strikes a good balance between understanding respect and for the ability to show dissent without disruption.
For the Arlington incident I cited earlier, when you are at a place that honors those who have given their lives to protect us, our freedoms, and our way of life, respect is to be shown, and disrespect should not be tolerated. That transcends rights and involves common decency and honoring the sacrifice made by others on our behalf.
If a person cannot be civil in a hallowed place, they need to be elsewhere.
The power and authority of government does not transcend rights. That's why they're rights.
The school handbook is just a further example of that abuse of power. "We want you to look like you're doing something you chose not to do. We don't want anybody to know you're exercising your rights."
