I have just made a connection - a twerp who used to teach a uni course I inherited used also to teach another course called something like "The legal theory of the outsider". When he ran off I had to do some of the finals marking (and it was clear that he had succeeded in leaving the students largely mystified) - but anyway, what UKIP demonstrates is the demagoguery of the same thing: blame an outsider, invent an enemy, vilify a minority - to consolidate the dutiful allegiance of a supposed majority.
