Authoritarian followers like simple things, simple thinking. Authoritarian leaders know how to deliver those. Authoritarian followers fear "the other" and complexity. Authoritarian leaders know how to prey on those fears. Hence, they rely upon the easy, time-worn scapegoats;
- gays
- women
- intelligent people
- people who look or behave differently
- people who believe other things or follow other traditions
There has been much talk of Steve Jobs "reality distortion field". While he was no conservative by any stretch of the imagination, he did share that one characteristic, the ability to create an alternatively reality out of thin air, then do everything in his power to make this so.
I grew up in a "conservative" household with all the trappings including the white fence (it was ranch-style, not picket). I was expected to believe and act on things that were demonstrably not true. Slogans, old-wives-tales and urban myths trumped reality. I was not allowed to believe the evidence of my own eyes. When I finally got out of that household, I had no tools with which to confront the real world, because up until that point, it didn't exist.
For authoritarian followers, it's simply safer to live in "the box", mumble the scripts dictated to them by their leaders, believe what they're told to believe and lash out at anything that could possibly make that change.
