As far as the US is concerned, I would have to say yes. This is my opinion. What is yours? We live in a divided nation-black and white, Asian, Indian, etc. There is a white culture, which stays all white. Can you guess the race of a Country /Western singer. It's no big secret whites harbor racists views. They interact with other races only when necessary, and certainly not live next to them. Blacks have their own culture, which stays black. Can you guess the race of a R&B/soul singer. They harbor racist views for other races. They also harbor a great distrust of the police. They interact with other races only when necessary, and certainly do not live next to other races. We have almost two independent societies. I believe it is difficult in the US for blacks and whites to shed racism. Both have unjustified fears and long, long traumatic histories.
Fuzzy, I beg to differ. Part of what you have said is true, the part about various kinds of singers being primarily one race or another. (Though even that isn't 100%). But these are cultural differences.
Many of us have friends primarily of our own cultural background; again, so what? That doesn't prove that "we live in a divided nation," although that may be true if you leave race out of the equation and just look at our social and political ideas. But having lots of friends from your own cultural background absolutely does not mean that we "interact with other races only when necessary, and certainly do not live next to other races." What ugly, prejudiced corner of the U.S. do you live in, and I might add, in what century?
It sounds as if you live in a world where people of different races dislike and mistrust each other. That is not the world I live in. In my building, people of all races and colorations live side by side, we get along and participate in all our activities together. (Or, at least we did pre-coronavirus). That applies to everything I do here. My bridge group, my theatre performance group, my scrabble group, my political club, the local newspaper I write for, you name it, we like each other and get along just fine. In my own experience, I think the Black neighbors are the nicest, friendliest people living here, and I am privileged to have them as neighbors.
So, where did "two independent societies" thing come from? I'm happy to say it is not true for me, or for most of the people living here. That's an ugly, suspicious way of looking at life, and at least in my world, not true. I'm sorry it is in yours.
