I bring this up because there's a lot of controversy over what people call those on the autism spectrum. Autism is a neurological condition that affects social development, making Erikson's psychosocial development model a lot more complicated over how to recognize autism being a part of one's identity. It could be said autism as a concept is in the adolescent years of "identity vs role confusion", as people argue over whether it should be considered an social identity (aka "identity-first") or something separate from one's overall characteristics (aka "person-first").
Again, I would like to reiterate that my feelings on my use of language concerning autism are my own and I won't dictate what others should do. I'm only using these posts on autism language to express why I feel that way I do and why I do what I do. I'm not gonna tell anyone how they should talk about autism because it's not my place to do so and I don't want people angry with me over it. This is just how I personally feel.
With that in mind, let me explain why I prefer "autistic people" over "people with autism".
