im 20 for reference. ever since i was a kid, up until hs, we were forced every morning to stand, look at the flag and hold our hearts and say:
“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”
i didnt stand a single time because i disagreed with being forced, and i was berated by the teacher in front of everyone, and he threatened to kick me out of class if i ever did it again. i was about 11-12 then, it was 2015.
I grew up in Florida and Tennessee in the 80s and 90s. It was definitely a daily thing, but very lax enforcement and I don’t know that anybody would have made a huge stink about it even then. The duck and cover “tornado” drills were very real and very serious though.
