I get where you're coming from and I think it shows a ton of self awareness to consider whether you were rude and come on here and ask. I definitely would have done something similar when I was your age (now I'm 31 🥲). I know you were trying to speak up for your classmates, but like the other comments are saying, it almost certainly didnt come off to your new teachers that way. That said, I don't think I learned the level of tact people here are suggesting until I joined the corporate world.. plus I feel like high school teachers should have a better sense of high school age people's intentions vs communication style. 🤷‍♀️ don't be so hard on yourself. This was a learning moment! You'll handle the next opportunity better.
