Yeah I agree.

I'm autistic, have a sense of justice being the result of reasonable clear fair and as objective as possible rules being consistently followed...

... but you don't need to be autistic to adhere to that. You can be ethical, moral, hold yourself to a standard, determine the reasonability of said standard, without being autistic.

Also... neurodivergence is more broad than just autism.

ADHD is a form of neurodivergence. On its own, I don't see that as being inherently relevant to rule comprehension, consideration or adherence, beyond maybe more complex rules or contingent rulesets taking more effort/exposure/practice to understand, consider or adhere to.

Schizophrenics are neurodivergent. Their ruleset often frequently changes considerably, due to reasons they often cannot explain coherently, and/or the rules they'll tell you they follow can be incoherent/contradictory.

DID is a form of neurodivergence. Each different identity often has its own significantly distinct ruleset / approach to rules.

Being bipolar is arguably a form of neurodivergence. Such people essentially have two rulesets that they alternate between.
