In middle school, my friends and I would stand like everyone else, but we’d say “One nation, under nothing” (we didn’t believe in God), and change the end to “liberty and justice for some” (or ‘none.’)

I wish I could say we were ahead of the game, but really we were just smartass kids who were resentful that we had to make a stupid pledge every day. I can’t speak for the others in that group (since we lost touch in high school), but I just straight up stopped saying anything at a certain point. I’d stand, no hand over heart (for those outside the US - the pledge is meant to be said with your right hand over your heart. I know, it’s cringe), and just zone out for a time while everyone else droned out the obligatory oath in bored, robotic voices.
