The parameters of discrimination based on race are distinguished by the power dynamics. Reverse racism is not, therefore a reality if people of color are not in positions of power and perpetrating the discrimination. An Urban Institute study shows that less that 100 of 3000 cases could be considered reverse discrimination. Less that six of those cases were deemed by the court to be substantiated. In reality it is a kind of social restitution and an attempt to create a more democratic society.
Affirmative action is an attempt to facilitate a more level playing field.
Affirmative action recognizes the interconnectedness of race, class, gender. Many of the symbolic gates are beyond reach due to economic disparity which in turn is one of the effects of racism. We cannot divorce these interconnected issues from one another. Beginning with the consideration of race as permissible in university admissions, in the Regents of the University of California vs. Bakke, the court rejected the notion that the constitution prohibits considerations of race. In the UC system, race and ethnicity are not solely considered for admissions.
