I once in high school was told about a thing I couldn't do to basically "just do it" by a teacher. In a meeting about my support network. My mother almost wanted to hit the teacher in the head with the dossier.
Maybe some of them, but some people are just legitimately stupid beyond repair in a neurotypical way. It's not their fault, it's not a moral failing and they deserve empathy and respect. It's just very unfortunate in today's society.
You know you can also analyze satire and comment on the hypothetical people involved in them too, right? Because satire is supposed to be a way to draw attention to real-life problems?
I don't think there are many hypothetical teachers going around and commenting on there students like this. They sure as hell won't have there jobs for long
And yet we absolutely do have a problem of very neurodivergent kids simply being called "stupid" and "a brat" by their teachers and being told to "stop it" and "just be normal" instead of, you know, the trained professional in child education recognizing those symptoms and referring parents to various resources for their child.
See? Satire. You exaggerate and make comical a real world problem in an attempt to get people to recognize that while it may not be as extreme as in the fictional piece, it definitely is a problem that is happening.
