I agree that affirmative action IS institutional racism. Let's get rid of it. Of course, slavery started in what became the U.S. 400 years ago and continued until the end of the Civil War. After that there were other forms of institutional racism, such as segregation, at least into the 1960s. As a result, non-whites and their descendants have been denied freedom and economic opportunity, and as such they are an injured class and entitled to a just compensation. I think if they were justly compensated, through some form of reparations, then affirmative action would not be needed.
Is that what you're suggesting?
