I do get where you're coming from @SusanStoHelitsPoker (I think at least - see what you think when you've read this and apologies if I'm still being offensive!) I definitely bristle at the "but everyone is a bit autistic, aren't they?" line (usually with a patronising head tilt). At the same time, I do believe I'm autistic, and my daughter is diagnosed autistic - and yet we both move through the world far more easily and with less danger to our freedom and physical wellbeing than my friend's son who is a non-verbal 12 year old who likes to play in roads. Now, in many ways he seems very happy, loves school, he has lots of great things going for him. But his experience of the world is clearly in many ways more challenging and dangerous than mine.
My DS has no Dx and seems very unlikely to get one, yet he has lots of similarities with my DD and me, compared to his NT peers (not to say he is not NT but also he does have some ND traits, for sure, as does my OH - definitely some sensory issues and some social overwhelm that I recognise).
But I agree it's much more complex than a line with "very autistic" at one and and "a bit autistic" at the other (or maybe "not quite autistic" in my DS's case), and I don't want to suggest that - I like this cartoon's way of putting it:
the-art-of-autism.com/understanding-the-spectrum-a-comic-strip-explanation/
I suppose what I really want is a way to recognise that some autistic people have a much harder time than others (and also that some NT people are more similar to us and "get it" more than others).
It feels a bit fake to just call myself autistic and play no heed to the fact that I live in a little bubble where my autism doesn't really cause me much problem (and I'm hoping that over time I'm hoping I can help DD build a little bubble that is safe for her in the same way), because I can just not do most of the things I find difficult (crowds, romantic relationships, customer service jobs, noise, being told what to do, not knowing what's happening next, being subject to somebody else's decision making on my behalf) - when there are other autistic people out there who don't have that luxury.
I think it's a tricky one. It just makes me feel like a fraud if I gloss over the differences. Nevertheless, it's a fundamentally common neurology (in my view), for all the differences in the scale of the daily challenges we face. I don't think it's a coincidence that my daughter is ND or that my son has ND traits or that most of my friends are either Dx'd ND or have strong ND traits.
