I see it in Star Trek all the time too. My namesake, Stamets, is a character in Star Trek: Discovery who is gay. He’s the first gay main Trek character in the entire history of the series. Honestly it is the only real depiction of homosexuality across all of Star Trek in general. When he was introduced as a character, he was just the science guy. Then two or three episodes in, he breaks his nose and goes to sickbay to get it treated. A Doc, Culber, treats him and is snarky to him. At the end of that episode, you see Culber and Stamets brushing their teeth together in the same bathroom and you realize they’re actually a couple and together. That Culber was being snarky and bitchy because the man he loves injured himself and is being a dick, not because he’s just a dick character himself.
That was in 2016 and the backlash was white hot and while it’s died down a bit, it’s still there. I constantly see people saying that “Oh why does he need to be gay?” or “Being gay doesn’t add anything to his character” as if being straight does. It always just boils down to “I don’t want to see that because I am made uncomfortable by gay people” 100% of the time.
Getting real sick of flagrant homophobes trying to pretend that they give a shit about the quality of a TV show and whether something is shoved in or not when there are more unsightly straight romances than there are stars in the sky and no one seems to give a flying fuck.
