Here it is. From what I can gather, this 'model' has been around since sometime after WWII. Before then, political thinkers referred to the Nazis as a socialist movement. As I pointed out responding to #98, this model makes no sense logically.
It says that the far left exposes centralized control and group rights/liberties and as you move to the right you get greater degrees of more decentralized government and individual rights/liberties. But suddenly, when you get to the far-right you suddenly revert to a draconian centralized control and ultimate group think with no individual rights.
Yes, it is conventional wisdom --- but it is also completely illogical.
