I know better than to argue with you about water and chemistry. Few people on Moparts have your level of expertise.
H2O has no charge and no desire to swap electrons. The same goes for ethel glycol. However, all the other crap in water is conductive. I'm not sure how many people use distilled water in their radiators.

Mixing tap water with coolant will become conductive easier than a distilled water and glycol mix.
