'Insecure, defensive, rigid people' tend to be drawn to authoritarian and repressive organizations. The actual political ideologies are less important than we think.

Here is a list of groups and movements which I would call authoritarian and repressive; note that in many cases their professed beliefs are quite different from each other, but their 'psychology' is quite similar:

Taliban, US 'Religious Right', Russian Communist Party under Stalin (c. 1945), Cultural Revolution in China (c. 1970??), Robespiere (French Revolution), US torturers at Abu Ghraib, Joe McCarthy, Spanish Inquisition, Salem witch trials, Nazi Germany, . . .
