How can two Authoritarian regimes be at polar ends of the political spectrum? Yes you were taught that but you need to look further back to the difference between the Authoritarian states of Europe and the founding of the United States. The current geopolitical battle illustrates this well. Authoritarian state China and constitutional republic of the United States. Freedom and dictorship are polar sides in the struggle, socialism and facism are almost the same thing. One is mob rule, the other is military rule, both are dictatorships with zero freedom.
