Although the comments were difficult to take and thank goodness already edited before I read them, in fairness to JP, it might be interesting to know, there are actual parents of autistic children who still wonder about the "refrigerator parent" explanation.
I think the disability in its basic form is quite severe. If you add bullying, abuse, neglect, to the picture, it is a lot more severe for some kids.
Normal kids typically express their experience of such things differently. They have a strong Self-Concept and are able to tell you what's wrong.
Some ASD children for whatever reason have trouble with the concept of a separate self. They are more likely to repeat behaviors of which they have been the victim or recipient.
You can see why the child ends up bearing an enormously disproportionate amount of blame and pressure for his or her condition, behavior, and coping mechanisms.
Now, toss in sensory differences, brain differences, allergies and other sensitivities that go along with this.
It is a clear case of square peg being brutally forced into a round hole in way too many of our schools.
I have a caseworker assigned to the situation with my own child, and before he started avoiding me recently, he said "that school ought to have been reported to the state ombudsman", regarding actions taken to "control" my severely disabled child's behavior at a school that likely overspent on construction and literally left special ed hanging.

owie.
P.s. since all that my child's been moved to a more capable school district and home.
