People are obsessed with Frozen and trying to force Elsa specifically into becoming gay. It's no longer about wanting representation, it's specifically about wanting Elsa from Frozen to be turned gay. #giveelsaagirlfriend was huge, even a lot of people who flat out said they don't watch cartoons or didn't like Frozen were participating in that, many saying they want it to happen specifically to piss off all those homophobic parents, and after that the media has been trying to twist clickbait from whatever "I don't hate the idea, it's nice that people like the characters" comment from the creators they've managed to get.
For example, Idina Menzel said in an interview in 2014 when asked about what she'd like to see for Elsa in Frozen 2 that she'd like it if Elsa found a "gentleman friend"; and then seemed to correct herself and backtracked saying she doesn't know anything definite about her sexuality, she's assuming that she's straight, uh. I'm assuming she'd been told to give no definite comment over Elsa's orientation.
This however, Idina's first answer being "I'd like her to get a male love interest", was taken as some sort of confirmation that Idina totally supports gay Elsa 100%, secretly pushes for it, and is sort of dropping hints between the lines by saying that she's not sure of her sexuality by people on tumblr and elsewhere. I saw that interview paraded around as if she'd have said "I'd like for her to get a female love interest, I think that's the way she swings"
People see what they want to see.
