This is the only time so far I've seen "fallacy fallacy" used correctly and not being used, ironically fallaciously, as if it automatically cancels out every fallacy in a person's argument automatically making it valid.
Or when objectivity is not called for. All those fallacies and "unfair strategies" are described as they are in order to keep objective discussions at said objective level. Yet, when the discussion by it's nature cannot be objective, none of those "fallacies" apply as fallacies.
Besides: An appeal is not a bad tactic in any way, shape or form.
