My Teacher Is Making Me Go Into The Hallway During The Pledge Of Allegiance

Location: Louisiana

I'm not sure if this is actually something that matters or that could, but I'm petty and want to know if this is legal. Just for context, I'm a junior in high school and go to a pretty chill school for this type of stuff, so this really hasn't been an issue before.

This all started a few weeks ago, when my English teacher pulled me aside before class to talk to me about me not standing up for the pledge of allegiance. She told me that it was disrespectful of me to stay seated, but I disagreed and we moved on. I think she did this twice, but I'm not sure. She got another teacher (he shares the same classroom with her, our class is basically taught in shifts in there) to talk to me about it too, as well as our principal.

They aren't legally allowed to make me stand or say the pledge, so I just didn't. A couple weeks passed and then she pulled me aside once more, yesterday, telling me that I need to stand outside of her classroom during the pledge, and that she consulted the school board lawyer or something. She also asked our principal. I sat in the hallway today (in the middle of it to attract attention to the problem bc this is dumb and truly unnecessary) and followed what she said, but I kinda just want to know: is she actually allowed to do that?? And if so, what would the punishment be if I just didn't listen to her and sat in the classroom during the pledge?

Again, idk if this actually matters or not, she's just annoyingly persistent with this and it feels wrong to just let her do this. I could be overreacting to this but I truly don't know.
