We currently have separate tags for autism and asperger. In 2013 the DSM-5 changed Asperger Syndrome to fall under the general umbrella of the Autism spectrum. However, there is a distinct culture and community of individuals with Aspergers, and treating it as merely a subset of Autism seems inaccurate.
There are currently 7 questions tagged autism. 2 of those are also tagged asperger. 4 of the remaining 5 are pretty clearly about people with High-Functioning Autism (HFA).
There are also 3 questions tagged asperger that do not have autism.
Should we use autism as the catch-all tag, for both HFA/Aspergers related questions, and for questions involving people who may be elsewhere on the spectrum, and that we also add asperger when it applies?
