Just in case, I will critique in the spirit of the original article:
The first immutable law of madeupistan is that this article makes no sense. If one quantifies by Q the amount of sense this article doesn't make, and divides it by L, which is how badly the sense it doesn't make is, one can plot the result on a graph, with axes and everything like in science.
As you can see by even a cursory examination of the diagram, anything can be positioned from "scotsman" to "no scotsman" on the Y axis, and "sense" to "no sense" on the X axis. This explains the fundamental nature of mankind.
The second immutable law of madeupistan is that your position on the scotsmanian axis is irreversibly determined at birth. You may be confused initially by the observation that even someone with a high degree of scotsmanity will sometimes act like a non-scotsman and vice-versa. Never fear, that is explained by the graph.
The fourth immutable law (and, by extension, the third) is that anything can be proven by decomposition into a punnett square.
The fifth immutable law is that once someone has been determined to be a scotsman, they will take actions without any basis in rationality whatsoever (I will heretoafter call these actions "Just So" actions). Note, though, that as per the second law, sometimes they will not.
The danger of these Just So actions is inexplicably large, and it behooves any non-scotsmen among us to immediately seek out and prevent Just So actions by dangerous scotsmen. If we do not do this, society will collapse.[1]
