The screencapped comment from _https://autism-all-stars.org/autistic-literal-thinking/_explains yet another absurdity: the notion of "common sense" and the inconsistency of "common sense's" application.
In all fairness, that situation sounds completely unreasonable and most people would be bamboozled by it.
@selffellatingouroborosofhate you seem to think that people don’t believe autism exists. That isn’t the situation, but there is an argument (as made in the book from the OP) that it, and other neurodiversity, is being overdiagnosed and also that some accommodations are not practicable in most of the settings we have.
As an example, you can’t refuse a place to a child with an EHCP because you’re oversubscribed- but in a specialist centre all the children will have EHCP, so at some point you will be full up and have to refuse people. The system is utterly flawed and cannot cope with the rising levels of need, so some way will have to be found to adjust things. The argument is, what things? Could more people with less severe needs make their own adaptations and could school policy make that easier (rules around uniform, for example)? How would that affect the kids who need really rigid rules to support their behaviour? Are there people being given EHCP who actually don’t need them? Does that mean other people aren’t getting them because of the finite pot of money?
Neurodivergence is not the only thing that needs accommodating- and I agree with pp about inclusion. It’s great for some, like children in wheelchairs or who are deaf but who absolutely can be in a mainstream setting, and appalling for others. I started teaching at the time when it was getting going and we all said this back then, that it couldn’t work for everyone. As another illustration, some teachers (eg in RE) see half the kids in a school over the fortnight, maybe 15 classes of 30+ kids each, and needs to be aware of and accommodate everyone who has any modifications needed (from MyPlan all the way to EHCP). It could mean photocopies on coloured paper. It could mean wearing a microphone or remembering to sit Kevin at the front and exaggerate lip movements. It could mean remembering that Tracey needs a desk at the back on her own. And all the other kids and school processes might not help those processes, because Tom and Jeff want that desk at the back, and Kevin hates being sat at the front, and there wasn’t any yellow paper and the photocopy technician is off sick. Or your child was up ill for three nights and you haven’t got to the planning for this class until that morning. And your classroom is so far from the staffroom where the toilet is that you haven’t had a wee or a drink since 7:45 this morning. Where teachers are accused of being uncaring, these are often the circumstances they’re operating in. And on top of all that, they are expected to show progress with each child, no matter what is going on around them, and have perfect paperwork and data, otherwise they could easily be put onto a competency pathway and lose their job.
