Again, I like that Luna is bisexual, but it's not even treated like a big deal, nor do they ever just outright call attention to it: she's dating a girl, and it's just treated like it's normal, nobody even questions it. Well, except for those morality groups like One Million Moms, or homophobic viewers, lol.
I notice the fandom really, really wants Luan to be bisexual; even though the show has her crushing on a boy in drama class (who's also crushing on her), they seems to love shipping her with an emo girl she never even interacted with.
