This was an extremely conservative area, and so my teachers were very upset. I told them I don’t have to say the pledge if I don't want (and I believe I had even memorized the specific court case with the Jehova's Witnesses about it). This went on for a week, until I was eventually sent to the principal's office for it.
The principal asked why I wouldn't just say it, and I told him because I don't believe in God and I don't have to. He said "well let's just see what your parents see about that". He picked up the phone and called my house, and my dad answered.
The situation was explained, and then my dad said "why is he in trouble again? I'm pretty sure he doesn't have to say it if he doesn't want to."
The principal responded back with "well sir, it's very disrespectful if he--".
My dad interrupted and said "it doesn't matter if it's respectful, if he doesn't have to say it then he doesn't have to say it. You should probably send him back to class". I went back to class and nothing that day came from it at school.
I was slightly afraid that I would get in trouble when I got home. I knew my dad had fought for me but I thought that he might have just wanted to make sure I don't get into any official trouble, so when I got home I was prepared for a lecture and maybe being sent to my room.
My dad sat me down and said "You're not in trouble, you did what you thought was right, but why does it really matter if you have to say the pledge? It'd probably be easier if you just said it" and I quickly responded back with "because I don't believe in God and I don't think I should be forced to say it."
My dad basically said that if this important to me, then he will support me. He wrote a note explaining that he doesn't have an issue with me not saying it if I don't want to, signed it and put his phone number if they have any questions, and he said to keep it in my backpack and show it to teachers if there's ever an issue.
I love America most of the time, but I think America can be great even if there isn't mandatory indoctrination. I look back and feel grateful that my parents were pretty cool with this.
