@Emerald@Melatonin honestly it's just that we have a very different social style in general.
Allistic social patterns are focused heavily on social hierarchy and group dynamics, which we couldn't care less about (see identity theory of autism, "group/organization/association based identity vs values based identity".
As far as allistics are concerned we tend to be "overly blunt", "too matter of fact", "condescending", etc etc.... mostly because we don't include all the subtle nods to social standings and hierarchy in our communication.
