Why do black people complain?

Black people have had it much harder then Jews. Black people really did not get rights in America until the 60's. Jew are evil they have controlled black people for yrs. and used black men as its tool. Convincing black people that biracial people are black. Helping black people to go extinct. In 2050 its predicted that most black people will look like Alicia Keys. Saw this on CBS
