You bring a few issues which can be turned into separate articles. But this one just spoke to me:
I can understand why a person who struggles with ambiguity finds it easier to retreat into prejudice instead of wrestling with that ambiguity to better understand it.
It seems that prejudice is a natural trait of humanity because it creates a world with less ambiguity. If so, then overcoming prejudice is a feat that is going against our nature.
I have been having interesting conversations with a couple of people about my Tiered Democratic Governance. I claim that for the TDG to function well, humanity must shed its natural instinct to accumulate power and control. My Medium colleagues do not believe this is possible, so we have to stick to western democracy as the best means of governing ourselves. Yet I would wager these same two people would also argue that humanity needs overcome its natural instinct for prejudice. So why is one instinct conquerable and the other is not?
