I don't really have much to say about today's Supreme Court decision on affirmative action. Given that there were 4 different opinions written, the whole issue seems to still be in much dispute. The continuing Court opinion is, I think, that affirmative action is legal (but as expressed today, not required) in education to address diversity and other goals.
My only thought on this is one I have had a long time about colleges and diversity. Universities are, if anything, institutions based on ideas and thought. So it has always been amazing to me that university diversity programs focus not on having a diversity of ideas, but on have a diversity of skin pigment and reproductive plumbing. In fact, if anything, most universities seem to be aspiring towards creating an intellectual monoculture. Diversity of opinion, of politics, and of general outlook among prospective students are not even decision-making variables in any educational institution I know of. And within the faculty, many institutions seem intent on purging from their ranks any single voice that diverges from the majoritarian view. I could have probably found more diversity of political opinion in a 19th century London gentleman's club than I can today in many campus faculties.
