I've seen this said several times, and at the risk of having my ears boxed
by the real scientists on the list, I have to say it looks like nonsense.
The loss of an electron gives a positive charge. That's not oxidation.
Oxidation is picking up an oxygen atom and thus becoming part of a
compound -- an oxide.

Any argument with that?
