Classic syllogistic fallacy, too!

    All electric currents transport charges
    Students transport charges
    Therefore, students are electric currents

  All things that transport charges are electric currents.
  Students transport charges.
  Therefore, students are electric currents.

It could be that we disagree on what it means to define something.
