My mom sucks!

My mom has such high expectations for me but barely any for my older brother! She says it's because he has autism. So autism means he can get away with being 17 almost 18 and throwing a tantrum in public while I get in trouble if I roll my eyes or am rude to our server in a restaurant. But he gets to have full on tantrums. And before anyone says talk to her about how I feel, I TRIED! I tried not even 20 minutes ago and she gets all sarcastic and says "So you want me to hold my expectations of your autistic brother to you a nerotypical teenager". I told her she could lower her expectations for me so they are equal and she again gets sarcastic and says "You want me to lower your expectations to your brothers. So should I expect you not to make it to the potty on time? Cause I can get you a pull up right now". She starts lecturing me about how she expects different from me yet my brother is OLDER!
