The way I look at it is that arguments are either factual or normative. Facts can be easy to test even if they are counter-intuitive. Normative, since you can't derive "is" from "ought" alone, means you are ultimately resting the conclusion on moral or value-based axioms. While people can reasonably disagree on the value axioms themselves, there might still be logical errors in the implications that flow from it, so it can still be useful to engage in a dialect to test for that.
