But that's not what happens, despite what people seem to think. On average 1 of those students will be Autistic, but also 3 of those students will have ADHD, 2 or 3 will have "personality disorders", 2 will experience childhood trauma, 1 will be a high-testosterone child assigned the sex "female" at birth, 3 will have specific learning disabilities and 1 or 2 will be considered "gifted".

When half the class isn't neurotypical, being neurotypical isn't any more "normal" than having blue eyes is "normal".
