Alanna Whitney is autistic. But she doesn’t talk about her diagnosis the way most people do. “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.” As WaPo’s Sandhya Somashekhar explains, Whitney is part of new group of adults who have banded together to start a movement. “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.” As you might imagine, the reactions to the movement span the spectrum.
