Suppose we divide the political landscape into four parts from left to right. The center is occupied by the productive and the compassionate. They engage in a rational discussion about how to make life better and how the good fortune of the most productive can be shared with those in need. They often disagree but respectful disagreement is the only way they know how to manage improvement in a complex environment. As soon as we get more than two people involved in a project things become complicated.
We can separate the “far” left and right from the center simply by their refusal to allow free speech. When people are not allowed to say stupid and hateful things we miss the opportunity to observe what idiots they are and how little attention they deserve. When I say something stupid, which happens from time to time, my friends will call me on it.
On the far left and the far right there is no room for discussion. You will do as they say or you will be attacked, de-platformed, lynched. Observe the KKK on the far right and the Cancel Crowd on the far left.
