Here are some thoughts to ponder. Teachers in every subject have their quirks, their likes and dislikes.
I know many college profs, and a fair number of them love fantasy, and even have fantasy displays lining their offices, everything from Lord of the Rings to Star Wars.
Fantasy/Sci Fi- People tend to love it or hate it to begin with. I'm sure that's in all areas of life. When I went through college I had to take required courses with teachers I disliked, disagreed with, and wished would get kicked out of academia. Still, it's about getting through and not about changing the collegiate world.
At least a third of my profs were stubborn and arrogant people, meaning they were never going to change. They would screw you for demeaning them and their sacred point of view, and they're no less sanctimonious with their fellow teachers. So, it doesn't really pay to take them on in a fight. If you read about Tolkien, he discusses the constant war between the Lit and Lang departments. They had two different worldviews. And editors constantly tried to correct Tolkien, because of some bias towards words "Dwarfs/Dwarves"
I once had a conversation with a group of agents. Very few would even consider rep for fantasy, because they admitted they didn't understand it. They didn't read it.
However, if you look at the top movies of all time- if you remove "Titanic"- the rest have a sci-fi or fantasy element. Even Pirates of the Carribean is mostly fantastical.
