I was straining to think of a good example of the 'left-wing authoritarian' but I have definitely experienced it, and apart the location of birth they are the same exact people who are just as intolerant on right.
On aggregate all humans operate pretty much the same everywhere in the way they think and operate -- the only difference is experiences and culture. That was the the point I was making -- we are never going to be rid of the people responsible for throwing wrenches in the political works.
Tangent: I think the only way this gets fixed is by putting a benevolent AI in charge of everything.
The problem, of course, is that none of them were actually left-wing. They were all just bog-standard dictatorships, using left-wing-ism as their excuse to maintain power, but not actually doing left-wing-ism.
But if I don't have any alternatives, I'd much rather have the "you can't burn wood in your fireplace" people in charge than the "force people to live as the gender assigned at birth" people.
One of those people is pushing policy that ultimately saves the human race from making the planet uninhabitable, while the other is imposing their small-minded religious worldview on people who have nothing to do with them.
And this is the thing that bothers me so much with the "both sides are just as bad" argument. Yes, agreed, they are, when it comes to listening to each other with empathy. I totally get that frustration, and I'm sick of the left/right culture war; both sides are to blame for perpetuating it.
Further, I think it's unfair to say that these two groups have more in common with each other than people who can listen with empathy; you're just comparing two unrelated axes of commonality.
