General Discussion

Metathesiophobia, agnostophobia, neophobia (fear of new things) and xenophobia. All of these can be seen to be working. Moreover, the anti-immigrant policies that so characterize modern day right wingers around the world, play to fear of the other, which is often tied to scapegoating ("they are eating the pets" ).

Scapegoating is closely related to fear of the other:

"The ego defense of displacement plays an important role in scapegoating, in which uncomfortable feelings such as anger, frustration, envy, guilt, shame, and insecurity are displaced or redirected onto another, often more vulnerable, person or group. The scapegoats—outsiders, immigrants, minorities, 'deviants'—are then persecuted, enabling the scapegoaters to discharge and distract from their negative feelings, which are replaced or overtaken by a crude but consoling sense of affirmation and self-righteous indignation."

Finally, right wingers create fictional problems to overcome: rampant attacks by drug gangs of "illegals" seems to be one of these themes. Facing a common threat enhances in-group cohesion.
