Again, my point is not about a particular power dynamic, but instead about a cultural dynamic: that people who expect a thing of others often get that thing, and in America, an expectation of danger and distrust leads to those very things.
You propose that muggers exist because we imagine them to be? I think you've reversed cause and effect--we imagine there are muggers because there are.
I'm less interested in the "cultural dynamic" you perceive than how you dealt with the "power dynamic" you so unfortunately encountered: Why didn't you defend yourself? And why scorn others who do? This complete debasement of the individual is incomprehensible to my American mind, and what drew me to your post originally. It seems to dominate other societies, so I would sincerely like to understand what system of values produces it.
It makes sense that a society should not allow harm to come to innocents
I specifically said, "violence," and not "harm," sir. As awful as our healthcare system can be, I was speaking specifically of mugging, and why you find self-defense more reprehensible.
