Social awkwardness is a component of ASD, and can be a huge burden for people with it. It really doesn't matter whose definition we go with for what constitutes "proper interactions." Clinically speaking, ASD can cause people to have a difficult time with verbal communication in general, and reading cues of people. This goes far beyond just being too honest.

The inability to make friends due to the behavioral issues that arise from living with ASD is torturous. It's probably why ASD is also linked with depression. If I weren't intelligent enough to work a technical job where people don't need to interact me, I probably wouldn't be around today.
