From what I've read there's been a history of people not fitting the strict "Asperger's boy" type traits being excluded from autism diagnoses, so we end up with a narrow, wrong stereotype. Plenty of autistic people who outwardly appear antisocial and plenty who appear quite social. Also worth remembering that autism occurence significantly overlaps with other conditions like ADHD, which may mold the presentation of the traits.
