[WS:] It is a form of logical argument called reductio ad absurdum http://en.wikipedia.org/wiki/Reductio_ad_absurdum
I used it too in my replies to you. Wojtek
--------------------------------------------------------------- "When a candidate for public office faces the voters he does not face men of sense; he faces a mob of men whose chief distinguishing mark is the fact that they are quite incapable of weighing ideas, or even of comprehending any save the most elemental — men whose whole thinking is done in terms of emotion, and whose dominant emotion is dread of what they cannot understand. So confronted, the candidate must either bark with the pack or be lost. [...] All the odds are on the man who is, intrinsically, the most devious and mediocre — the man who can most adeptly disperse the notion that his mind is a virtual vacuum. The Presidency tends, year by year, to go to such men." - HL Mencken ----------------------------------------------------------------
