Here's how it works for the non-Americans of us:
"I pledge allegiance to the Flag of the United States of America, and to the Republic for which it stands, one Nation under God, indivisible, with liberty and justice for all," should be rendered by standing at attention facing the flag with the right hand over the heart.
Remembering this often-forgotten detail puts a lot of US culture and behaviour in perspective. Also let's not forget the Bellamy salute, in use for 50 years until 1942: https://en.wikipedia.org/wiki/Bellamy_salute

There most certainly is not. The pledge is common in schools but the Supreme Court has ruled no one is required to participate and cannot be punished for non-participation. Is it still weird? Sure. But it’s not required.
I always disliked the Pledge and began to strongly dislike it after moving away from the religion it tries to establish as the national religion, but I was keenly aware that picking this fight would cost me considerable political capital and chose not to.
How many schools still do it, though? Honestly you could tell me it was almost universal or very rare, and I'd have to believe you either way.
Of course, Canada was doing the freaking Lord's Prayer in schools until freaking 1988. I don't know about other countries, but wouldn't be surprised.
What sort of consequences? I'm guessing the US got rid of corporal punishment, and since it's optional, could they give like detention and stuff for it? Or is this more about being bullied/similar by peers?
