I'm honestly not sure what the point of your story is, if anything, it was a surprisingly good result that the teacher was removed and the child wasn't abused any further, and quite gross that the protest was against this happening. Sounds like you agree with the protestors and were not happy with that result and think the child should have been subjected to even more scrutiny? Which is an odd point to try and make around a group of autistic people talking about being abused by schools and other institutions.

Literally last month an autistic kid was arrested and suspended for a "bomb threat" AFTER all they found his bag was a stuffed toy.

No, it's not ok. Disabled is the word you are looking for.
