Which is denied you when the person's argument is so ill-formed that it does not have a central point. At that point, you either point out the flaws or you walk away, apparently conceding the point to the pointless one.
That's a good, uhhhh, point. There are many people who form their arguments so poorly that it can be hard to refute them because they'll just move the goal posts or completely change the playing field.

(Also: I love the word point, apparently.)
