Success of politicians like Sanders and AOC on the left and Cheeto Mussolini on the right prove that people don't want moderates. Some people who would have voted for Sanders in the last election literally voted for Trump because he wasn't a moderate and they thought he would bring positive change (or because they decided they'd rather see the world burn than business as usual.) The DNC lost the last election specifically by choosing to field the "safe", moderate, business-as-usual candidate instead of a candidate who promised change.
Authoritarianism is a form of government characterized by strong central power and limited political freedoms." Check. But what if we examine the question in (slightly) more detail?
Create victimless crimes, imprison people (ideally in privatized prisons from which the ruling class gets kickbacks, or which they own) and then demonize them when they are freed to increase recidivism, because incarcerating the same people over and over minimizes the chance that the voters will notice. This is the right hand of the devil.
This diatribe is a response to a discussion containing repeated assertations of "false equivalence" between the Democrats and Republicans. I don't believe that individual Democrats and Republicans are equivalent, and I don't even believe that left to their own devices, the people who make up these parties wouldn't go in different directions. I believe that we have a system that permits the corporations to juggle us between these two parties, reducing them to a distracting false front that distorts our view of the actual situation: corporate governance.
