Is AUTHOR wrong in the post ? POST : (Sorry for formatting I’m on mobile)

I’m in my schools drama club and we were doing a play for a competition. After we came home from the competition we all stopped and took a quick picture. I thought it would be funny to do the little finger circle sign 👌 while we took it. (Stupid I know, but harmless right?) The school posted it on Facebook and the most that happened for a while is people noticed the sign, maybe did the breathe-through-nose thing and went on with their lives. The only reason that anyone cared is someone, I still don’t know who, called the school and said it meant white power. (I didn’t know about this, some cops got suspended for it once too) This, however, isn’t the main point of the post. My parents are treating me like demon spawn, not because they think it means white power, but because I would dare to make a joke in a picture. I would also like to point out that nobody who doesn’t think it means white power thinks it’s a big deal, including both drama club teachers, all of the students in drama club, many outside students, and even an outside teacher who I asked.

Sorry if this isn’t the right sub to post this, but I want to know your opinion.
