What does the term "reductio ad absurdum" refer to in debate and advocacy?

The term "reductio ad absurdum" refers to a method of argumentation where one demonstrates that a proposition leads to an absurd or contradictory conclusion. This is achieved by assuming the truth of the proposition and showing that it would logically lead to outcomes that are obviously false or absurd. This technique is often used in debates to undermine an opponent's argument by illustrating the illogical consequences that would arise if that argument were accepted as true.

By focusing on how an argument leads to unreasonable conclusions, debaters can effectively challenge the validity of that argument, making "reduction to an unreasonable conclusion" the most fitting description of this rhetorical strategy. This method not only engages critical thinking but also serves to reinforce one's own stance by showing the flaws in opposing views.
