Got into an argument with someone over whether a character is "non-binary."
The character's name is Zoe Hange, from Attack On Titan.
According to this other guy, in the manga in Japanese, for some reason Zoe's sex is apparently never specified, thus this guy insists on referring to her with they/them crap--he also uses this as justification for that whole Yamato thing. "See? Other series do this. Get educated."
The anime, however, explicitly makes Zoe female, and voiced by women in both Japanese and English--were she non-binary, she likely would have been voiced in English by someone who claims to be such, like Michelle Rojas or Marianne Miller (now calling herself Marin Miller), but instead she is dubbed by Jessica Calvello, who is a normal woman.
Yet this guy only refers to Zoe Hange as "they" and crap like that.
I am not into Attack On Titan. Not my thing. But unlike One Piece's Yamato, I can't find word from the original creator on this, and I don't trust sites like TV Tropes to tell me the truth here. Thus, I turn to you.
If the mods feel the need to remove this, I will understand. I'm just not sure who else I could ask this.
You 'win' by not having this argument, this is somebodies' sex fantasy playing out and the weirdo is trying to enforce it on other people by arguing about it. It's the equivalent of when women fantasise about their favourite characters being gay, it's almost certainly a fetish and the guy is taking it too far and you've already enabled his behaviour. Really the only one who can even decide that sort of thing in the first place anyway is the creator themselves, the rest is just nerdy fan fiction and that's what this is.
