Some say it is the movement of electrons and some say it is the movement

truth, Mr. Wizard?

The truth is that the electrons move, not the protons.

You've fallen into the trap you are complaining about and providing
a simplistic answer that isn't true under all circumstances.

I can think of no mechanism to move protons in a solid, but they
move quite well in a vacuum.

Ever heard of a proton accelerator?

A current flow in a proton accelerator is a current flow of protons.
