School Area Name for Autistic People

Okay, listen up, you smooth-brain. You see this joke? It's like, a thing where they use 'downtown' as a play on words with the area of a school where people with autism may be grouped, since 'downtown' is like, an area of town. So it's kinda mean to people with autism by linking them to a part of a school and calling them 'downtown' instead of 'people'.
