Growing up, we did not stand for the Pledge of Allegiance or the National Anthem.
As a 2nd grader, when they still did the PoA every morning, I was the only kid in class to not stand (was the only JW kid in that school actually). Until one day we had a substitute teacher. When I didn't stand, she grabbed me and tried to force me to stand. She held my by my elbow, forcing me out of my desk. I let my legs go limp and I hung there like a wet noodle. I never told my parents, but today I see lawsuits over similar instances.
When I was older, I planned my route to my seat at ball games and other events to miss the NA, so I wouldn't be obvious in my refusing to stand.
Now that I'm free of that indoctrination, I still do not Pledge Allegiance, avoiding the Nationalistic indoctrination. I do stand at both the PoA and NA, respectfully, quietly, removing any cap/hat I may have, but I do not sing or pledge. I am not blindly patriotic to any nation or government. I learned my lesson being blindly loyal to a religious organization. Won't make that mistake again.
