How autistic adults banded together to start a movement

Alanna Whitney was a weird kid. She had a strange knack for pronouncing long words. Anchovies on pizza could send her cowering under a table. Her ability to geek out on subjects such as Greek mythology and world religions could be unsettling. She drank liquids obsessively, and in her teens, her extreme water intake landed her in the hospital.
Years later, she found a word that explained it all: Autistic. Instead of grieving, she felt a rush of relief. “It was the answer to every question I’d ever had,” she recalled. “It was kind of like a go-ahead to shed all of those things I could or couldn’t do and embrace myself for who I am.”
So it came to be that Whitney, 24, was arranging strawberries and store-bought cookies on platters at the Queensborough Community Center for a celebration of “Autistic Pride Day,” her shoulder-length hair dyed mermaid green to match her purse and sandals. A bowl of orange earplugs sat nearby in case any of the guests found the ambient sounds overwhelming.
Whitney is part of a growing movement of autistic adults who are finding a sense of community, identity and purpose in a diagnosis that most people greet with dread. These “neurodiversity” activists contend that autism — and other brain afflictions such as dyslexia and attention deficit hyperactivity disorder — ought to be treated not as a scourge to be eradicated but rather as a difference to be understood and accepted.
