A Columbia prof teaches a highly diverse class of Columbia's famous and required Contemporary Civilization. He discusses in A Look at Real Diversity.
He concludes:
I have been teaching a class on Western Civilization since September.
It is highly diverse.
My brown students are no less -- but no more -- meaningfully "diverse" than the others.
And in our class, together in all of our diversities, we have had a multifaceted and utterly human journey.
I'd give almost anything to teach that course for a couple of years.
