"Fandumb" can be the layman's term while this can be used in an academic sense and setting. However, we should replace "autistic" with "neurodivergent" to cover more ground and to include more groups of people like the psychopaths and sadist-types that tend to occupy fandumb groups as well. If we can get a paper published with this terminology (I have a few ideas of how to do such a thing), we can do irreparable damage to them in a broad societal scope.
