The spectrum replaced terms like Aspergers & I’m not sure you really understand autism if you think they suffer sometimes. The idea of the spectrum is that the common symptoms of autism like sensory processing can vary greatly in how they present from case to case. Everybody has different ways they respond to light, noise etc but its only when these responses fall below a standard level that it becomes a problem & its only when several of these occur in a person that they get a diagnosis of ASD. You for example may not read peoples facial expressions very well - thats a common autistic trait but it doesn’t mean you are autistic just where that part of you measures on the spectrum. From that perspective everyone is somewhere on the spectrum.
We’re waaaaaaaaaaaaaaaaaaay off topic so I’ll leave it there.
