People call themselves "Jewish" as a descriptor of thier religion or as a identity pride as an ethnic group and other reasons. With "aspie" it is no different you have people that use it to describe thier symptoms or triats, others use it as a group identity. Some that identify as "Jew" or "Aspie" go no further other take pride in the identity while others go beyond that to feel superior to other groups.
People that describe themselves as Jewish are a spectrum also from people who follow every rule to those that are totally secular. Like aspergers some Orthodox Jews do not believe those less orthodox then them are not really Jews and fake Jews.
It is possible Autism as a condition does not exist. While in my view Autism is a seperate condition and Aspergers is a sub catagory of autism and not a totally different condition until there is a lot more evidence we can not be sure.
