Remember that study which came out in 2012 which said that conservatives were much more likely to be authoritarian personalities? Turns out it was a mistake and the opposite is true.
This makes perfect sense:
There's only one side which wants to clamp down on free speech.
There's only one side which prevents speakers from the other side from speaking.
And there's only one side which shows up at the rallies of the other side to disrupt them.
The authoritarian side.
