Definitely. It doesn't fit their narrative of "back in my day..."
Back in their day disabled kids weren't legally entitled to an education. Further back autism was infantile schizophrenia and mothers were blamed for being cold towards their kids in their formative years and autistic kids were put in institutions and mistreated.
I didn't go to a school with blazers but I did go to a school that insisted on those god awful ties with the elastic or clip where you had to have your buttons done up to the top, and I was chastised daily for taking them off and undoing my button, even going as far as being told I would make other people think inappropriately. I can't remember having friends, or any good memories of school but I can remember every time I was punished for feeling uncomfortable and getting detentions for not being able to cope but just being seen as defiant, and then more detentions for being too overwhelmed to do homework, or revision, or eat, or drink, or speak when spoken to. I do remember spending a lot of time out of school and under the hospital for malnutrition because I felt too unwell to eat every single day from school, and I remember having to have bone scans to check my bone density as I was always in pain.
I remember being bone tired every single day but too overstimulated to sleep at a normal time and being called overdramatic for not being able to cope with multiple people talking over me at once and just being reduced to "she must be tired" by teachers who then said it is my fault I should just get to bed at a normal time.
I remember getting labelled a psycho and bullied by kids I couldn't get away from because they'd seen me have meltdowns and used it against me, even telling my first boyfriend I'm his future psycho ex girlfriend and ruining my relationships.
Thank God there's more understanding of autism now and people feel safer pursuing this avenue, it's just a shame that there are so many people around who either lack the capacity to understand or are willfully ignorant to autism.
Maybe they don't remember kids with sensory issues or social difficulties but I bet they remember the class weirdos, or the crazy kids in their class, or the troublemakers and the distractions, or the kids that got "special" privileges and seemed to be favourited by certain teachers.
