This isn't a thread-about-a-thread but I wrote a version of the below in response to another thread that then got deleted before I could post it. I think it's useful information so thought I would start a new thread that isn't about one particular person but just general info.
Posting in AIBU because the original thread was here though.
The Autism spectrum isn't a line from "mild" to "severe" - it's like there's a colour wheel, and each person's symptoms are like a different cut-out shape across different sections of this wheel, so no two people with autism have exactly the same issues to contend with. There isn't a "mild" end of the spectrum which is almost the same as being a neurotypical person - NT people are not even on the same colour wheel at all. Terms like "mild" and "severe" are really unhelpful because they tend to refer to how much the issue is perceived by a neurotypical person. Someone can have a particular issue quite severely in terms of how much stress and difficulty it causes them, but may mask the issue. Obviously some people have much more significant challenges than others and may have additional conditions as well as the ASD, but people who are able to function to some extent in society don't have a less intense type of the condition, they are just affected in a different way.
