To start things of, I come from a Muslim somewhat conservative family. I, 18F, wanted to go to a small concert with my friend. It's from 8 pm and ends at 10 pm in downtown Chicago. Tickets are about $35 each. The concert is at bottom lounge, the website said it's for all ages and no alcohol will be served, even though there's a bar at the entrance of the area. My sister, 19F, is going to a Bruno Mars concert from 9 pm till 1 am.
She is going with a few of her friends. I don't know of the restrictions but I do know its outdoor and at this park in downtown Chicago. The tickets for that were $450 each. My mother is saying No to my concert because I cannot enter a bar, despite no alcohol present. She says the concert I want to attend is dangerous and can get myself into a terrible situation.
I argued with her about how it feels unfair and she doesn't believe in my character to keep myself safe in a situation and how it was a double standard that my older sister is allowed to go to that concert while mine is entirely safe and restricted. In the midst of the argument, I called her a bitch and said I couldn't wait to move out because she has always been this conservative about certain things. To her, being near alcohol dismisses your entire faith as a Muslim.
Was I the asshole for arguing with her about it and dragging my sister's event in the situation?? I feel very conflicted about what I'm doing because on one hand, there's an obvious double standard but on the other, I feel as if I'm acting outrageous.
Edit: Thank you for everyone's insight! I'm trying to fix the situation because I recognize I did screw up, but I would like to mention that I did in fact get kicked out and was physically harmed as a response from my mother. I purposely didn't include her reaction because I didn't want any judgement on that situation. I only wanted to know if I was an asshole after doing that.
