I have a common ancestor with about half of a tribe in Northern Canada. The people of Old Crow are primarily Gwich'in people. Before I told you about them, how much did you appreciate them? Are they good or bad. Are the lazy or industrious. Are they friendly or unfriendly. I can only describe my feelings for the ones whom I met. A couple of ladies stayed with us, when I was young. I was very fond of them. I think there great-grandfather was the brother of my great-great-grandmother. Their "grandfather" had moved up there over a century ago due to his profession and remained.

white people do not appreciate the blacks

People are the same regardless of their skin colour. If the above statement is true, than the following statement is equally true.

black people do not appreciate the whites

It isn't a skin pigmentation problem, it is a knowledge problem. You might have had that opinion your entire life if you never grew to know a person like me.
