I know. I’d be interested in a study of how the kids with the “tantrums” were treated (by parents, educators, and caregivers) for the three days preceding the “tantrums”.
If I was treated the way I see a lot of autistic kids being treated, I’d have a “tantrum” too. (Translation: if you can’t talk, and powerful people are gratuitously mean to you on a regular basis, what else can you do but act in a protesting manner?)
Mostly, AFAICT, the nightmare isn’t being autistic - the nightmare is having to try to learn from those teachers or live with those parents. I have students who are autistic - some with “tantrums” and some without - and I certainly see glaring differences in parenting.
It’s hard to grow up autistic if you have mean stupid parents, harder than if you’re not autistic. What a surprise.
