Does this actually happen? It sounds like a total caricature of what someone thinks city folk are like. I mean, I spent the majority of my life in cities of different sizes and also have friends across the entire Northeast and I travel a lot. Nothing like this actually happens. My extended family are casual racists and complain a lot about Puerto Ricans. Hillary was widely unpopular with everyone I know, liberal, conservative, and moderate. I don't know a single minimalist but know a lot of people who complain they are poor while buying a bunch of junk. When my house was broken into by unknown assailants a friend of mine said "It must be niggers." Nobody really goes around talking about political policies very much, it's almost never a topic of conversation. We are generally just a bunch of normal people and none of us actually do that stuff. We have different culture and mostly different activities than rural Americans but we are not at all like you describe.
We do go to restaurants, coffee shops and bars a lot but never because it's trendy. Actually now that I think of it that wasn't big in one of the cities I lived in.
>They are mugged and then bend themselves into a pretzel to avoid describing the attacker as black
This is absurd and nobody is bending anything. People i know who got mugged said "I got mugged." I do admit i never heard "I got mugged by a black man" but probably because that information isn't entirely relevant but no bending like a pretzel. Unless you believe bending like a pretzel means "not bitching endlessly about an entire race because of the actions of on person."
