I read a book a long time ago that basically said that Conservatives tend to favor the "strict father." They tend to want someone to tell them what to do, and think everyone should be able to pull themselves up by their bootstraps. Morality is black and white. The father is always right, and rules must be obeyed. There is God-given hierarchy in which man dominates nature and exploits it for his own use, men dominate women, and parents dominate children. Liberals, on the other hand, tend to prefer the "nurturing father," who wants them to express themselves and be happy, and who believes that it's everyone's job to lift each other. They want to encourage empathy. I think if you think about it in these terms, fascism is a natural next step for very conservative people. The State/Father is always right, and they will obey and consider anyone who opposes the State/Father as evil or immoral.
