Yeah, luckily, that seems to have stopped for the most part after grade school. I have been to a couple of events as an adult that did that, and it felt very bizarre.
My "favorite" part is that they are having kids recite a pledge knowing full well that most of them have no understanding to what it actually means. Taking a pledge should be one of those "I, state your name, of sound mind and body, pledge allegiance..." It's just one of those things that is so illogical to me that I don't get how it's not for everyone else
