Tell me which of the water molecules moved in two opposite directions

flow in opposite directions, either. It's the combined total of
forces that causes the movement of both charge and water. Two opposite
movements of either charge or water are impossible.
Nobody is arguing about that so it is obviously just a straw man.
The real question is: Can two EM waves travel in opposite directions
in free space or along a wire. The answer is YES!!! Standing waves
can exist in free space or along a wire. To deny the existence of
standing waves is ridiculous.
