Ursula K. Le Guin said this quote
“ I want to say to the literature teacher who remains wilfully, even boastfully ignorant of a major element of contemporary fiction: you are incompetent to teach or judge your subject. Readers and students who do know the field, meanwhile, have every right to challenge your ignorant prejudice. Rise, undergraduates of the English departments! You have nothing to lose but your A on the midterm! ”
