Radical right wingers favor hierarchy and oppose democracy. The extreme is Monarchy or Fascist Dictatorship in which the leader and nobility rule, and the rest of the people are ordered by race or class with the peasantry and non-white races having no political rights (or property) what-so-ever.

Perspective: liberals are inclusive, and conservatives are exclusive.
