Duality! The US democracy is based on the principle of duality. Most of the conceptions on Earth are based on that principle as well. For example, we compare good to evil. In different aspects of our life, that principle exists. In sport, we compare Leo Messi with Ronaldo. In Tennis, we choose between Nadal and Federer. In Formula 1, we choose between Hamilton and Vettel. In politics, we choose between 2 parties. It is a circle. In love, we choose between a man or a woman. Our world is built that way.
So, you are comparing good and evil to two political parties? A person should just which one is good and while is evil? I don't think it's that simple. How can you just choose 2 people from each sport and say we have to make some choice between them? What about Neymar or Harry Kane? I'd love to hear how you actually connect that to politics. How is choosing between two parties a circle?
