I’m gonna need the entire Arrowverse fandom to stop saying Sara Lance having a crush on Kara Danvers in the crossover is “queerbaiting.”
Queerbaiting is when writers throw queer subtext in as a joke between straight characters without any intention of follow-through. It treats queer sexuality as misappropriated “edginess” at best - as a way of having your diversity cake and eating it too - and as a punchline at worst. It’s there only to bait people who are interested in seeing explicit LGBT representation, but without the intention of ever delivering any.
A bisexual woman crushing on an ostensibly straight woman is not queerbaiting. It’s queer subtext, and it is still valid LGBT representation.
Straight people have unrequited crushes all the time, too. Sometimes you’re attracted to people who don’t feel the same way. That’s just life. This actually happens to Kara all the time - people want to be with her and she isn’t interested back. (See also: Schlott Jr, Winn.)
LGBT characters’ stories are allowed to have hits and misses just like everyone else. That’s still representation. And honestly, just because a lot of people find Sara hot doesn’t mean it’s an insult if Kara doesn’t.
