>T. AutistAutism is poorly explained even to people with the condition, partly due to DSM-5 actually doing away with strict diagnostic definitions. "You are on the spectrum" is what you're told, and you have to keep asking quite a bit before you're even told what that means and more importantly what it means for you specifically, because there are some extremely wide margins around a handful of shared problems.
Commonly you get things like low stress tolerance, but that's then the cause for much more "stereotypical" autism behaviors. The stereotype of needing to do everything according to tight schedules and planning for example is just a normal coping mechanism to reduce the amount of external stimuli that could otherwise easily overwhelm an autistic person, but it isn't actually a sign of autism by itself, it's not as if this is compulsive behavior for example.
It's then laughable to try and argue that something like "stacking or lining up is a sign of autism", that's not what OP's image even suggests (who could have suspected a /vt/ poster isn't properly literate)
