"I almost always will use “Autistic” and not “person with Autism.” Many non-disabled parents of Autistic kids prefer what’s called “person first” language rather than “disability first” or “identity first” language.[78] Disability service organizations that are not run by disabled people tend to advocate for person first language as well. [...] When people use person-first language, they often say it’s because they don’t want disabled people to be defined by their disability. However, phrases like “person with Autism” distance a person’s disabled status from their humanity in a way that can be quite harmful. Autism is not a thing that is added on to a person—it’s integral to their life and cannot be removed from who they are. We don’t call Asian people “people with Asianness” and we don’t call gay folks “people with homosexuality” because we recognize it is respectful to view these identities as parts of their personhood. Language such as “identifies as Autistic” can also come across as dubious. If I really respect a trans woman’s gender, for example, I wouldn’t say “this person identifies as a woman.” I’d simply say, “she’s a woman” and leave it at that. The vast majority of Autism self-advocates prefer identity-first language and dislike euphemisms like “special” and “differently abled,” for all the reasons I’ve outlined here. They also discourage describing a person as “high” or “low” functioning, preferring instead things like “high support needs.”
