They never will which is Unfortunate, There will always be Bigots and Racists but remember Rascism is not Inherited it is taught in the family, you are not born a racist you are raised to believe in Racism and Bigortry and that type of Hatred
I became "color blind "many, many years ago, when I was old enough to know what it meant you know what type of "Color Blind I mean)
Every groups of people has their good ones and bad one, there are bad Whites, African Americans ect. ect
But Racism is taught not Inheritated
