(from a recent interview with Harold Bloom on Blood Meridian)

AVC: You’ve been extremely critical of the politicization of teaching literature…

HB: Critical, young man, is hardly the word. I stand against it like Jeremiah prophesying in Jerusalem. It has destroyed most of university culture. The teaching of high literature now hardly exists in the United States. The academy is in ruins, and they’ve destroyed themselves

I showed Zack this quote and neither of us are certain of what "the politicization of teaching literature" actually is, can anyone throw light on this?
