Its been yearssssssssss ago since I studied this at Purdue EE School but as I recall there wasnt any "argument", the electrons (electron current) flows one way, while the holes (hole current) left behind when the available free electrons in the outer atomic orbit (what makes it a good conductor, abundance of free electrons) vacated, flows the opposite direction. There was some difference as what was referred to as "Conventional Current" which flowed from Pos to Neg in circuit diagrams used to solve math/engineering problems while "Electron Current" flowed the opposite. i.e. for current to flow one way in a closed circuit consisting of a battery and an external load it has to flow from - to + INSIDE the battery so it flows from + to - OUTSIDE the battery. Maybe Bob M can add to or shoot this down?? Again, its been many yearssssss so my old hard drive memeory may be faded lol
