AITAH for not listening to my mom and continuing what I’m doing?

TW!: unsupportive mom || swearing || slight transphobia AITAH for not listening to my mom and continuing to do what I'm doing? I (13)(genderfluid, but born Female) have been struggling with my identity, I've started to use "Maxi" as my name. I also volunteer at a summer camp, (my mom also works there) put my chosen name on my name tag. I had it on all day and I thought that she didn't see it, but when the day came to an end (around 12:15) I took the nametag off, putting it in my pocket. I sat in the car waiting after all the kids got picked up, my brother and I sat in the car waiting. My mom then walked to the car and started driving, everything was okay, she wasn't mentioning my nametag I had on earlier. I went into the laundry room (next to my parents room) to grab clothes for the pool when she called me into her room. She said "deadname, why did you change your name to Maxi? Can't you just be deadname again" I didn't have a response, I felt betrayed that she didn't see what was happening. I then nodded, saying "yes" when she asked "can you just go by deadname..?" I walked upstairs, my dad asking "What name did she use?" My mom responded "Maxi" I walked into my room, sitting on my bed because I was scared to say I'm genderfluid, because if that's how she reacts, I'm not coming out. The next today at the camp, I didn't care what she said, I put "Maxi" on the nametag again, she texted me "please put deadname on your nametag." I obviously didn't ! But she'll respect others, BUT NOT HER GODDAMN KID!

But AITAH for not listening to my mom?
