I haven't found a depiction of gay relationships in a mainstream show I haven't found a bit cringey tbh. With very few examples, the inclusion of a gay character is just for the sake of it. We are a minority, and there's nothing wrong with the cast representing the main bulk of the population who probably aren't gay.If your media has any gay characters, it's shit.
I don't really know most of the examples listed here, but from the ones I've come across being gay usually doesn't really add anything other than controversy/oppresion points and the story could have worked just as well with a straight character (Voltron) or they're J. K Rowling-esque retcons.
That and they try too hard idealizing them as something that belongs in Stepford fantasies.
