Well, labels are said to create difference and further pathologize Autistic people. After all, we're all the same, right? Well, no. As already discussed, the difference between neurodivergents (which includes Autistic people) and neurotypicals exists. (A Response to "But We All Are!") The erasure of an a label denies identity. Therefore, by denying the labels, an intrinsic part of the Autistic is erased. Without the outward expression of Autistic identity, a connection to Autistic culture is lost; meaningful connections between Autistic people with other Autistic people are lost. This is important. The mental health of Autistic people notwithstanding, the assimilation of Autistic people into neurotypical society is antithetical to the concept of neurodiversity which affirms the validity of all brain types. (Assimilation is not integration/inclusion. Please be aware of this.)
"But you're not defined by your Autism!" Yes I am. My world is the world as known, as experienced, as sensed by an Autistic. I share common traits with other Autistic people and share a more or less common Autistic experience*. You cannot separate my Autistic self from the rest of myself. Most of my formative experiences have been through the lens of Autism; those experiences definitely include school experiences. This has been covered many, many times.
*sort of. Sensory issues and society's coldness to it? Yeah, pretty similar for everyone. Anything more than that...eh. Not really. Autism is not the only identity which shapes me. All of them do and more or less equally. I'm not going to go around claiming I have the same experiences as every other Autistic and whatnot. Things are intersectional. *cough* white, straight, abled feminism *cough*
