No you misread my refutation, I make no claims of the errorness or exceptionness of dividing by 0, merely that your proposed example doesn't support your claim that it depends on the nature of the application. I claim that unchecked user input falls into the category of 'error' and that clearly is what has occurred in your proposed example.
I understand them to be saying that if execution is supposed to be halted before the division occurs, then whether the division is an exception or an error is a moot point.
