"But how will I know who has Real Autism and should be pitied and who has Fake Autism and is just being a jerk on purpose for inconveniencing me?"

Yeah.

Autism should have diagnostic subtypes because it is a varied condition, but singling out "aspergers" by itself was useless and the criteria were poorly chosen.

(I was diagnosed several years before the DSM V; my paperwork says aspergers)
