To people who feel deprived of a clear social identity, Ur-Fascism says that their only privilege is the most common one, to be born in the same country. This is the origin of nationalism. Besides, the only ones who can provide an identity to the nation are its enemies. Thus at the root of the Ur-Fascist psychology there is the obsession with a plot, possibly an international one. The followers must feel besieged. The easiest way to solve the plot is the appeal to xenophobia. But the plot must also come from the inside: Jews are usually the best target because they have the advantage of being at the same time inside and outside. In the U.S., a prominent instance of the plot obsession is to be found in Pat Robertson’s The New World Order, but, as we have recently seen, there are many others.
