I absolutely find it annoying when romance is prioritized over friendship but this isn't quite what queerbaiting is. At least, not on its own. Two same sex/gender people being very close and sharing a strong connection or even having some romantic undertones that never become "official" isn't automatically queerbaiting. Those things can happen in real life without those relationships being or becoming romantic. Queerbaiting is when the writers/showrunners purposefully insert romantic subtext into the story and advertise it as if it will become canonically romantic with the primary intention of gaining more lgbt viewership, while never actually following through on those implied (or even occasionally explicitly stated) promises. The way it is presented and marketed is an important part of what makes it a problem, hence the "baiting" part. There's nothing wrong with keeping a relationship ambiguous, or portraying a platonic relationship as being as deep, important, and emotionally intimate as romantic ones are typically portrayed without making them romantic, but if you try to manipulate or outright lie to viewers to make them think a relationship is going to be something it isn't in order to gain their viewership and support, only to pull the rug out from under them, then that's when it becomes sleazy, especially if you're taking advantage of the fact that they're a marginalized and under-represented group desperate to see more people like them in media.
I know this is just a joke comic so "it's not that deep" but I see a lot of people online who misunderstand what queerbaiting is and accuse shows/series of queerbaiting unfairly so I thought I'd bring it up.
