How old are you? When was the last time you were on a campus? Do you have to deal with any of these sort in daily life?
I went to school in the '90s. And I count a few of them amongst my freinds. Remember this is good old fashioned 'English'...not Woman's Studies or Queer theory Studies. Perhaps people involved with those other departments (who have connections to Lit Departments of course) would say differently. I went to a small state school. Perhaps the radicals are at the Ivy League schools? Though people I studied with studied with people like Stanley Fish who I don't regard as a radical.
