Diagnosis or not matters in the sense that it is useful intel for you and a tool. Just writing detailed essays and having strict logical structures in forums gets called autism on the internet. But if the internet communities for autism are useful to you and you are doing no harm that is good too.
Labels and definitions are useful in diffenerent contexts, and I would encourage you (and everyone) to (continue) applying them only as appropriate and beneficial to wellbeing and growth.
I like the oxford method and defining words and concepts before discussing them with people. You are being very transparent about what subclinical-autism in your case means. I think that honesty is very good and what helps prevent harm.
Someone doesn’t have to be Capital A Autistic with clinical presentation of Autism Spectrum Disorder (>pet peeve: disorder is in the name people! If you are NOT feeling disordered, you likely don’t have ASD!<). But being autistic in character or presentation on a subclinical level is valid too. And there are a lot of valid reasons why people cant receive that diagnosis. I know some severely autistic people that arnt diagnosed formally with ASD. I like the words autistic or neurospicy or neurodivergent for that, rather than ASD. I am now adding ‘subclinical autism’ to my list. Such an interwsting concept.
I think a lot of fights within the community stem from lack of oxford method definition, argument in bad faith. People conflating terms.
There are conditions that look a lot like autism, but are not. Other possibilities to consider are a high IQ measurement, OCD, ADHD, or a number of related conditions. All valid. Self-discovery is very valuable for personal development and I would encourage you to explore what voyld be the root causes of the phenomena you are experiencing, while also not leaving the autistic community which benefits greatly from your honest participation.
The precise bounderies the particular evaluator uses to determine ASD can at the minimum contain info about the local autism landscape created by that person who works your area. For better or worse. It’s useful to know what definitions that are being applied to people by a professional in your local area. People with medical authority and considered well qualified to diagnose ASD are not large in number at times within a local area, so very much influence the local definitions.
Establishing definitions is so important when communicating with people, local or otherwise. The concepts circle back to the Oxford method again.
