"you're either Autistic or you're not"
Which is exactly the point being made when I point out the difference between an actual, clinically described disorder, and someone merely using the terms improperly. Those people claiming to be "a bit OCD" about something very defininitely do NOT have Obssessive Compulsive Disorder.
You say I'm ableist, but I'm not sure you realise I'm deliberately targeting people who claim to have Autistic Spectrum Disorder, when they clearly have not even the slightest difficulty with their lives and would never be diagnosed thus by any medical professional. Same for those who claim to be dyslexic, rather than just being slower readers or academically lazy.
In short, a casual misuse and abuse of terminology* by people who haven't the first clue about what actually constitutes a mental disorder, often as an excuse for their poor behaviour, and doing a great injustice to those who actually do have such a disorder.
*"On the spectrum" being a typical example of such misuse. This time take note of the very intentional quotation marks. I used them for just such a reason.
Having better explained yourself, I understand on a re-read where you came from. I also apologise for grabbing the wrong end of the stick. This part however,
Most people are "on the spectrum", but they're just mildly deviant from average social norms. They don't have an actual disorder.
to be fair, was ambiguous and did place the opposing slant on much of the rest of your post. Your clarification makes sense, and I agree with you. As someone who does have a formal diagnosis, I spend my life being quietly infuriated by throwaway comments about 'not looking Autistic' or reassured that 'everyone's on the spectrum to some degree'... As you say, the debilitating reality of a disorder that rules and shapes your entire life, and the self diagnosed Face-agram 'Autism mom' lifestyle are very different beasts.
