Yes, there is tremendous, self inflicted ignorance about most of the planet. It once was simple ignorance as the nature of the “ugly American” but now it is politically motivated distortion. This is being used to wall off the frightened minority and keep them open to autocratic protection.
The hard part is the crumbling of shared assumptions that erode all western representative government systems. I very much appreciate your introduction of some basic reality to counter the most absurd ideas but we’re in the process of a much bigger and more challenging transition. There are no simple answers.
