This discussion of capacitors reminds me of the interminable
philosophical discussions about how many angles can dance on the head of a
pin.
... If the process of charging a capacitor is discussed with reasonable
care, most - if not all students - understand that one plate ends up with
an EXCESS of positive charge, while the other ends up with an EXCESS of
negative charge. In most - but not all - case the capacitor remains
neutral.
