reductios ad absurdum

Elizabeth Warren's Unwarranted Wage por Walter Block:
Murray N. Rothbard used to say that it is impossible to convince the economically illiterate with reductios ad absurdum. Why? This is because the very purpose of this type of logical argument is to embarrass our friends on the Left (and the Right too, sad to say, see below) by taking up the premises of their proposals and applying them to cases not contemplated by them. But suppose they are unable to be embarrassed? Suppose they cannot grasp the fallacy of their own position even when it is obvious to all of those with even half a brain? Then, while the logic of the critique is impeccable, it still cannot convince the intelligence-deprived true believers.
