Number one reason I want a functional conservative opposition to my preferred progressive politics / party.
Cause I, and my fellow progressives are probably dead wrong about some things.
Communism (people above state) and Fascism (state above people) both resulted in the same deliverable: homicidal maniac dictators.
The one type of person I can never trust is the person who says "I'm not wrong"...
Agree !
Not only am I mostly unaware of my own cognitive biases, I know that they exist.
Without other rational voices, to point them out, I would be walking down a dangerous path.
Not just the lessons from history, but the deep awareness of what is really going on now, can stop me from my own mistakes. This most often comes from others, and not my "best" thinking.
@XSGeek The US has a history of this happening. In the 19th century the opposing party was decimated. I've heard historians describe how it lead to social unrest.
