Haven’t court decisions rendered pupils’ participation in the pledge of allegiance optional in all 50 states?
random aside, there was a kid in my Texas high-school who stopped saying the pledge around the time of the 2003 Iraq war. While I didn't necessarily agree with the method, a few of us did appreciate the fact that he did that; it showed that sometimes the most patriotic thing you can do is not blindly support your government.
Source: I was an Australian citizen while in US schools from 2nd through 12th grade. It can be highly uncomfortable to stand silently (and politely) during the Pledge.
For example, a Colorado teacher physically assaulted a student for not saying it: https://kdvr.com/2018/08/31/teacher-accused-of-assaulting-st...
Another teacher just tried the guilt trip approach: https://fox2now.com/2018/11/16/teacher-banned-after-students...
It's just something the kids say, the school isn't building it up or making it a huge deal or forcing them to believe in it like it's the only thing that matters.
Comparing this to China's brainwashing is a huge slippery slope IMO.
I think in terms of US school problems, this one is pretty low on the list. I would be far more worried about general quality of the schools, curriculum, "active shooter drills" and other insane safety measures, and increasing lack of funding for basics like acceptable landscaping and art/music classes.
It is a “small thing” of course compared to comprehensive political education, but it is a thing and signals the start of a trend that could turn out to be dangerous (doubly so in this age of Trump-style ultra nationalism).
Saying the pledge of allegiance in school has been around since I was a kid in the 80s though, and I'm fairly certain it's been this way since basically forever. So IMO it doesn't seem like it's the "start" of anything.
Unfortunately, I’m a bit worried about American schools, many now require daily pledge of allegiance here in Washington state, which was definitely not true when I was a kid. It just feels like something China would do but the USA shouldn’t.
