I'm a librarian who loves anime, manga, and reading a wide variety of genres.
Some interesting reading. From a quote in the article:
"Because the majority of professionally-made media is catered towards a straight white male demographic, leaving little room for 'outsiders.' Outsiders who, if they want to see themselves in media, have to attack it and change it — hence slash fic, hence long essays claiming that Hermione Granger is black, hence [headcanons] about trans characters or genderqueer characters."
