No need to apologize: this is your journal. I just don't want to have to deal with a flame war in the community, and it always distresses me to see newcomers lynched for reasons they don't understand. We refer to Asperger's Syndrome as Asperger's Syndrome, though many of us abbreviate it to AS or ASD (for Autistic Spectrum Disorder[s]). Most of us refer to ourselves as autistics or as Aspies. We also use autistic or Aspie as adjectives for characteristic behaviors or thought patterns (the word symptom[s] tends to go over badly, but not as badly as disease). Person with autism gets bad reactions too; after all, no one would refer to our president as a person with blackness. Autism is part of who we are, and cure would be tantamount to death, kind of like in that classic movie, Invasion of the Body Snatchers. And as you surmise, NT is a convenient abbreviation for neurotypical.
