A man and a woman being a couple, clearly in love with each other. The man helps her out, cares for her, would die or kill for her if it came down to it.
The fandom: you know what, I just don't see it. Them being in love being both stated and shown? Don't see it. Y'know what, I think they were actually queerplatonic. Here's an essay against canon evidence, actually. No of course this has nothing to do with misogyny! I love women...I acknowledge when they suffer...sometimes. Also, look at that! Their relationship was not perfect! Aha! What's the point then?! This was clearly abusive! Anyway, I'm going to ship this man with every possible male character that was introduced instead, even though he didn't even like them and liking them actually goes against who he was, and I'm going to invalidate and discredit the canon ship at every possible turn, until people who ship the canon ship will be made feel bad for liking it or posting about it.
I'm going to hold your sexist head when I say this: people are allowed to ship whoever they want in fanon and to not be crazy about a hetero canon ship, but if you cannot see that fandoms are incapable of incorporating and caring about the female character from the story and only acknowledge her seperately from time to time, and almost always make it about the men she is surrounded by instead, misogyny is deeply rooted inside you. When the canon ship is discussed, it's always criticized and invalidated until people who like that ship are discouraged and tired of speaking. People cannot even acknowledge canon and things that came from that love without pulling teeth. But they're all for coming up with increasingly toxic dynamics for every male character and consider it cool. Pushing away the female character and replacing her with a male counterpart. There is no valid reason to not be able to celebrate an interesting canon dynamic, the fanon will still be popular, especially here.
The fandom: Oh my gosh, wait. The female character had a brother! Let's switch to that instead!
