Right wing authoritarianism has nothing to do with the US political divide. It is called that because the French parliament back in the day had the monarchists/authoritarians sitting on the right side of parliament, while the liberals/anti-authoritarians sat on the left side of parliament. Many communists are right wing authoritarians.
One trait of high authoritarian people is the capacity for cognitive dissonance. This can be accomplished in many ways. I know, for example, that your definition of "mass democratization" is very different from what I would consider mass democratization. You have clarified this when defending North Korea.
The concept isn't very muddy at all. It's not even necessarily a bad thing to be authoritarian. However, highly authoritarian people often do not like being known as such. Interestingly, they would like to be seen as average authoritarian, while both medium and low authoritarian people think that being low authoritarian is best.
