Given that a large number of 'English' teachers, professors and instructors were and are dyed-in-the-wool members of the Modern Language Association (MLA), I think that they would do away with English itself if they could figure out a logical way of doing it. Being that logic is not their strong suit, they just continue with fond paeans to deconstructionism and Marxist rhetoric.
As for Science Fiction, it was a SF Author Ted Sturgeon, who formulated the best reply to criticism of the genre when he replied that 90% of EVERYTHING was dreck. I think in the original there was another word used instead of dreck ...
Sturgeon’s Law. Yes, the original was more pithy.
Since I was in school, SF has gone from proscribed pariah to a graduate degree course of study; from sub-counterculture, to mainstream.
Better pay and markets for the authors, but a lot less fan-fun and freewheeling fan-pro mixing at the conventions.
