Racist karen mother gets mad at me on a bus

I am a 23-year-old Arabic woman, I was born in the United Arab Emirates and moved to San Francisco when I was 13. A few weeks ago, my friend (another Arab girl) invited me to a big party at her house, it was on a Saturday night so I was a bit hesitant since I had church on Sunday Mornings, but she convinced me to go. I got dressed up and I wore a short black farasha and a sheer veil (something I've worn to all formal events) I don't drive and I don't like paying for a taxi or uber, so I got a bus to her house. I sat in the front and the bus ride seemed fine, towards the end of the ride a young girl came up to me and said "I love your dress, it's very pretty" I thanked her, and then her mother stomped over to me and told me to stop talking to her child, I rolled my eyes and she got very mad at me for that and began yelling at me about how I needed to "go back to where you came from" I just sighed and cussed her out quietly in Arabic, she heard what I said and began screaming at me and causing a huge scene, "SPEAK ENGLISH YOU INDIAN BITCH" I was shocked and just stared at her silently then said as calm as I could "I'm Arabian you dumbass" and got off at my stop, I told my friends at the party and we all laughed it off.
