> Traditional explanations for the black-white test score gap have not stood up well to the test of time. During the 1960s, most liberals blamed the gap on some combination of black poverty, racial segregation, and inadequate funding of black schools. Since then, the number of affluent black families has grown dramatically, but their children’s test scores still lag far behind those of white children from equally affluent families. School desegregation may have played some role in reducing the black-white test score gap in the South, but school desegregation also seems to have costs for blacks, and when we compare initially similar students in today’s schools, those who attend desegregated schools learn only slightly more than those in segregated schools.

Automatically blaming any discrepancy on outcomes between different racial groups on racism isn't helping anyone. It also doesn't really feel like you're looking to discuss or learn anything here, rather just to scold people for being racist. This is a tough question that doesn't have a solid answer yet.
