Sidreal has conceived of a rather elegant and clever way of depicting one’s stance on the issue. Still too complex for sound-bite, energize-the-base politics, but very useful for quickly understanding the nuances (and there are many) to an individual’s position. For the record, my own personal curve is concave (or positively parabolic, if you prefer) where sidreal’s is convex (negatively parabolic), but its beginning and ending points are pretty much the same.
