I see the autism spectrum as one half of a much longer spectrum, one that runs from the extreme pole of full autism (mind-blindness to others) to full borderline (mind-blindness to oneself).
A person (or group) unbalanced toward the autism end of this enlarged spectrum will proudly refuse to care what anyone else thinks. A person (or group) unbalanced toward the borderline end will feel existentially threatened by the thoughts of others, because the thoughts of others is the sole source of selfhood for the borderline personality.
The ideal, of course is the middle region, where we are aware of what others are thinking, feeling and intending, but we remain rooted in what we ourselves think, feel and intend. Even when we consider changing our views, we do so as ourselves, making an evaluation and decision.
This ideal is represented in my Geometric Meditations book in the symbol of the spiral.
