Pledge of Allegiance is literally some stupid shit some opportunists made up to sell flags to schools with fat government contracts.
It's also just sort of creepy to idolize a flag. I always stood for the pledge in school out of respect for the freedoms I enjoyed, but refused to put my heart on my chest to worship a piece of cloth. This was in the 90s.
Nowadays I don't even stand for it because everything's gone to hell and I'm just constantly mad about it all.
