Autiaro (or autiaromantic) is a romantic orientation on the aromantic spectrum in which one's autistic traits affect one's romantic orientation/lack of romantic attraction. Autiaro is not autism as an orientation, but rather an aromantic identity that is so heavily affected by or influenced by one's autistic traits, that one's aromanticism and one's experience of being autistic cannot be unlinked from each other.
Not all autistic aromantic individuals identify as autiaro. Only those who feel their aromanticism is influenced by them being autistic. Autiaro is an exclusive identity for those who are on both the autistic and aromantic spectrums.
The asexual counterpart is autiace.
Autiaroflux
Autiaroflux refers to those who are both autiaro and aroflux. Of course, autiaroflux doesn't describe every autistic aromantic, just like autiaro. Also, like autiaro, it's exclusive to autistic individuals.
Flag
The colors on the flag come from the aromantic flag, and as such, they represent the aromantic spectrum. The infinity symbol represents the autism spectrum.
