Obama's relationship with black universities

This is a [rather scathing] commentary on President Obama's rocky relationship with Historically Black Colleges and Universities (HBCUs).  I am not in the circle of people who went to HBCUs nor do I have many friends who did, so the whole background of the cultural milieu of these universities and the President's lack of familiarity with them, coming himself from a more Northern upbringing, was new and interesting for me.
