Injustice Against the Black Race

I have always wondered and ask questions as to why the black race is treated with comtempt and disdain, seen as never-do-wells. Each time a great achievement is attained by blacks there must always be a way to discredit or discard it, all efforts will be made to sweep it under the carpet in order not to be heard or talked about or shift the glory to white counterpart who may have contributed little or nothing to it

However, the case is different when it comes to negativity and crime. The crimes committed by blacks are blown out of proportion to make it seem like everything about blacks is evil.
Come to think about it, in cryptocurrency ecosystem there has been a lot of swindling running in mult-millions dollars perpetrated by the white and nobody is talking about them, but when a black man steals 1000$ the world must know about it.
Can someone please answer why is it so. I'm confused I need help
