I know, shame she fucked off really. But she can't deal with being questioned.
It's obvious from her initial post that she was expecting to be greeted as some sort of "big sister" and respected veteran. She is so clueless. I agree with the narcissistic personality disorder suggested above, but still say she must have borderline as well.
She probably abused the hippie-community and every other community she tried to be a part of the same way she's doing with AS. She projects her delusions onto others and preaches the One Truth while trying to attain an iron grip on others. In her own eyes, she is the high priestess of Aspergia.
Her hunt for an identity makes her identify as "aspie" when the problem is really her overall mental state. She probably has a long history of taking entire communities hostage when trying to forcefully mold them in her own image. This is an aggressive borderline/narcissist behaviour but she seems so tragically unaware of it.
