Why shunn

There is scareful racism in not only Korea, but also all of the world.
Why is racism exist?
At view point of children, they are scared fearful things, especially people whose appearance is scary.
That is because children are too young to know whole things.
Thus they see people who have black skin dreadful
because black color gives us some meaning like scare, dark, dread.
It can be forgiven because they are young but if they are adult, it should be changed.
Racism is based on appearance-important society.
But, it is too bad that people think lightly of black person only because of skin color.
It really give them feeling frustration.
How stupid people who discriminate are!
