From the introduction to Finn V. Gratton’s Supporting Transgender Autistic Youth and Adults:
Finally, language related to “functioning levels” (e.g., “high-functioning” and “low-functioning”) will not be used, unless it is part of a quote or a study. The term “autism spectrum” will not be used because it generally refers to a one-dimensional line that extends from point A (those people perceived as furthest from allistic functioning) to point B (those perceived as most like allistic people). This verbal and mental construction posits a one-dimensional view of human experience and expression that places allistic experience and behavior as superior to autistic experience and behavior. Where differences in functioning matter, for example in the case of autistic individuals with low speech abilities trying to access services, I will note the distinguishing characteristics that affect the autistic person’s life.
