I agree. No one is black or white. We are all shades of color.
We make this big weird rainbow of tan, peach, cocoa and mud.
You're forgetting a colour: the Mongoloids. Yellow, some may say. There are three races of people: *******, europid and mongoloid.
They differ from appearances: hair, skin colour, lips, nose, etc. But we've been mixed so many times over the years, that there isn't really a lot of pure 'white' or 'black' left. Some live in Africa, but most got at least one ancestor from a different race. To answer your question: I personally think that there aren't any black or white people anymore, but some in Africa and some minor groups over the rest of the world.
But the whole society makes people black or white. It's in our nature. Racism, that is.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
