I think this passage from 1984 represents religious fundamentalism as much as it does any totalitarian government:
"Even the humblest [church] member is expected to be competent, industrious, and even intelligent within narrow limits, but it is also necessary that he should be a credulous and ignorant fanatic whose prevailing moods are fear, hatred, adulation, and orgiastic triumph.
In other words it is necessary that he should have the mentality appropriate to a state of war. It does not matter whether the war [on Christmas, on the family, on marriage, on Christianity] is actually happening, and, since no decisive victory is possible, it does not matter whether the war is going well or badly. All that is needed is that a state of war should exist."
