In addition to queer headcanons, I also get annoyed with people making trans headcanons, especially if the character never shows any indication whatsoever of being trans. Or even worse, a person acts outside of the gender norm (ex: a boy crying and being sensitive; told to "be a man!") and some sjw uses that as fodder to cry "TRANS CHARACTER!! PROOOOFFFF" Like first off, that's incredibly gender normative-- thought people didn't like that. Plus it's a huge disrespect to the character.
While I agree with you that it’s gender normative to AGAIN try and force certain characteristics onto SEXES and their assigned, idiotic gender roles ( dear SJWs, I love beer and I love hot girls and their secondary sex characteristics, and I love BBQ and ice hockey and have a horrible sense of humour playing all kinds of awful older-brother-esque pranks on my siblings as a child that usually involved either fake blood, caterpillars, frogs or jellyfish - I’m still happily a girl, thank you, now get off my ovaries), I don’t really understand what you mean with “a huge disrespect to the character”.
Like, do you mean “not true to the character” as in claiming something IC that is definitely OOC? Which I might actually go along with. Or do you mean, uhm… that it would be the worst thing to happen to someone to be trans* and so “forcing” this fate ontoa character would be humiliating, thus an act of disrespect? Because then I actually wouldn’t agree with you. (I don’t think you meant the latter one, though.)
It’s the first one, but with a bit more of an explanation as well. You see, I like to see characters as “people”, in a sense. Obviously they’re not actually real, but that doesn’t mean they don’t have personalities of their own. And I feel as though, since these characters have solid personalities based on what they do in canon, there’s certain things you can think about and assume, “Oh yeah. They totally would/ would never do that.” So when someone says, “Yeah, I think Luke would wake up one day and decide he wants to be a girl, and start wearing girl clothes and telling everyone to use girl pronouns around him and call him Luka,” I’m gonna have to say I don’t agree with that. Of course, statistically, it’s possible; anything is, really. But based on what we see in game and the anime and everything else, it’s not probable in any way. Luke never has any problem identifying as a boy.
When someone applies a trans headcanon to Luke (or any cisgender character) like that, well it makes no sense to me, because as far as anyone can rationally see… he doesn’t want to be a girl. So I think for someone to say, “No you’re wrong, secretly he does want to be a girl,” I find that offensive to him as a “person”. If he were someone sitting in this room, I can guarantee he wouldn’t agree, and he might even be offended that someone would make such assumptions about him with no basis. In a way, a person applying a trans headcanon like that is erasing part of who the character is, and that’ s not fair.
I’m not saying people can’t make queer or trans headcanons, I’m just saying they need to make sense within the context of that character’s personality, because it wouldn’t be fair and genuine otherwise. Obviously there are cases where people can make queer or trans headcanons that make total sense. Like a lot of people think Dist is in love with Jade, and portray that in fanworks of all kinds. This, from the obsession Dist has with Jade in canon, is a pretty plausible assumption even if it’s not canonically true (is it? does anyone even know?).
I’m not trying to hate on queer or trans characters or anything like that. But I think it’s just really wrong to erase part of who someone is and the choices they want to make in their life— even if they’re not real— just because someone thinks that makes them “cooler” or more interesting, or as a means of making some political statement.
