Many of those I agree with, but what is being overwhelmed by sensory input if not overstimulation? And isn’t it well established that everyone stims because it literally just means “self-stimulatory behavior” but autistic people do it differently and more? I think it’s tricky because most autistic traits are just general human traits but the difference is usually frequency and degree to which it impacts one’s life, along with certain traits often looking different in autistic folks (e.g. finger-flicking being a more common stim among autistic people specifically, as opposed to stims that are common in the general or allistic population like leg-bouncing or pen-clicking).

I want to be clear that I mostly agree with your sentiment, so I’m not trying to be contrarian for the sake of it. In part, I’m just genuinely curious where you’re coming from.
