That's arguably true from one point of view and I can see why you're saying that. I guess what I'm saying is I feel like it should be more ubiquitous to both right and left thinking. For example both right and the left generally speaking can agree that murder is bad even if we don't agree on what we should do with murderers. Some things are outside of the realm of left and right.
I think is a society we should come to an agreement that certain extremism whether it's left or right is horrible and wrong. And there was a time when that was a generally accepted belief. "I disagree with what you say but defend to the death your right to say it". etc etc.
When I was a younger person there was a great deal more belief in the idea that repressing speech or repressing people or groups or any sort of authoritarian Behavior be it on the right or the left was unacceptable and would like to see that pervasively agreed on by both sides of the spectrum again.
The Hallmark of a free and successful society is its ability to be tolerant of multiple and often conflicting ideology and still find a way to work together on those things we agree on.
