80s movies were fabulously awful in that way, which probably is
   part of their endurance value. I believed the John Hughes
   stereotypes for a long time - still shaking them off.

   Thank you for your astute analysis, and yes, it appears the
   person who made the observation was using Sociopath in the
   common form, as a catch-all that includes sociopathy,
   psychopathy, anti-social personality disorder and Aspergers,
   among other often lumped together "pathologies". [I'd prefer to
   call them personality types but I gotta stick with the context
   even if I disagree]
