In the late 1980's to mid-90's, the level of internal crime in the United States increased alarmingly. And many of those related to these crime were black-colored.
When a white-colored man used to snatch away from other white people; Then the created fear was less than the fear would have been created when the hijackers' skin color was black.
This happened once with the grand mother of former US President Barack Obama. Although she had been caught by several white robbers before but, she was not so scared like this time. Obama's grand dad did not want to give importance to this matter; there was a reasons for it too. Their grandson was a black !!! 
Obama came to know about the incident later. He was somewhat hesitant about his identity. He is not white nor black. The young man, who is in a skeptical, went to an old wine-house that night to meet the sadness of his mind. He was seen there an African-American family friend named Frank. Obama told him everything.
Frank told Obama that night - "Look, the white know what they have done with blacks. So whenever any white person got hijacked or encountered such crimes by a black; then they are less afraid of hijacking, they are more afraid of remembering their own previous crime" !
The white people have done so many wrong thing to the other colored people for a long time. After the First World War, they have started doing the same injustice to the Muslims. Which is still running at a very fast pace.
Everyone aware about their own crime. So they feel scared to remember those. The American feel scared, the British feel scared, the Chinese feel scared, the Pakistani, the Turkish, the Russians all feel scared. Indians are scared too just like the Burmese. That's why they seek freedom from their fear by expelling all the Muslims from their region, just like Hitler,Churchill and Stalin.
According to the history none of them were successful. Their wrongdoing still chases them and their country. Their wrongdoing made Barack Obama the president of the USA . Sadiq Khan, the mayor of London. And the fall of Berlin Wall.
The creator do'not like injustice. He do'not like emptiness either. He might have kept us empty now. But he will fill us in the right time. Because, he is committed !
