Would this piss you off?

I met my brothers girlfriend today. I brought my son along with me. He's 11 and has autism. His girlfriend was talking to me and then started asking what was wrong with my son. He was covering his ears and rocking back and forth. I'm guessing he got over stimulated and was trying to cope. I told her thats just his coping skill and he has autism. She says "Autism. As in another word for spoiled." I got very mad and told her no hes not spoiled. He's autistic. It's a real thing. Sbe says in the most stuck up voice ever "Listen. I'm not trying to judge your parenting, but autism really isn't a real thing. It's parents not wanting to tell their brat no. My kids don't behave like that." I said "Well congratulations, your kids don't have to deal with struggles everyday that people like you refuse to learn anything about and make them feel bad." My brother told me not to talk to her that way in his house and I told him "Fine, I won't be in your house." I don't think I'm wrong for popping off. Also I hate how she said she wasn't judging my parenting but she obviously was!😡😡😡
