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]
