The resilience of the “American two-party system” finally and thoroughly explained

I hereby suggest that the ongoing tenacity of the two-party system in the United States is the unavoidable collective trajectory (tragictory?) of a preponderance of minds incapable of modeling social reality in ways more complex than the hyper-over-simplified notions of “good” and “evil”.

Each side, in effect, is satisfied with believing and/or concluding “I'm right, and you're wrong!” – not to mention hair-triggered to manifest outrage, protest, and shunning toward anyone expressing views more nuanced their own uselessly simplistic fundamentalist modeling.
