Racial differences exist because of the way people view things. They only choose to look at the surface of something and judge it accordingly. People will only ever be able to get past these problems if one thing changes.
That they stop looking at everything on the surface and realize that biologically and spiritually we are all the same, human. There are no differences that are worth fighting over. It'll require an entire change in the way we think for everyone to accept each other unconditionally in this world.
Of course it is not, even animals treat the different differently. Human should be better than animals but somehow our basic instincts show on surface in bigger crowds.
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.
