Harry’s interested in girls. Hermione’s interested in boys. Fred asks Angelina to the Yule ball. Hagrid’s interested in Madam Maxine. There’s Bill and Fleur. Remus and Tonks. Heterosexual couples are littered throughout the books.
And then, after the books are published, once all is done and dusted, she comes out saying that Dumbledore is gay? I don’t want fucking subtext for queer folks when I’m smacked in the face with heterosexuality at every turn.
