A widely reported problem on here is the common reaction to someone explaining their autism is "oh i get that too".....etc.
I think because people on the spectrum are relatively isolated, there's little opportunity to chat experiences and get feedback. So people on the spectrum don't know what problems are fairly common in the NT world, and may not be autism specific.
I've just posted on the question of hearing sensitivity/filtering sound on another thread. I've found that the problems I've had are reported by others not on the spectrum, including people with dyslexia.
I wondered if others had found that some things they associate with autism are more widely present in the general population (but not just a matter of degree as with spectrum - tailing off into the general population - but similar levels of difficulty experienced by people not having autism which is otherwise assumed to be an autism characteristic).
If that makes sense.......
