Actually, anyone that has issues with the number of nyms another person uses, has issues. You do not need prayer, you need a rubber room to accommodate you until you go back into the Earth.

Or perhaps this is new material for some of our readers: a negative charge (+1 electron) is certainly "compensated" (insert your favorite synonym here) by a positive charge (-1 electron). Go figure!
