Source-Autistic is a term for people who identify as having autism because they had it in source
It can also be used for those who already have autism, but experience it to a different agree, those who’s identities relate to the autism they have in source, despite not having it bodily, those who experience autism due to having it in source, and many, many others.
This is not necessarily I wish I had autism/I was meant to have autism feeling. It is moreso ‘I am autistic because that is who I was in source’
