I deeply dislike this framing, where Hussie has absolutely no agency. If her only demonstrated attitude is apathy, if her position is to not present, seek or ask others to view them as transfeminine, and instead to use a queer identity to deny a gendered presentation altogether, then I don't see how it's at all viable for me to then go ahead and decide on my own who is right and who is wrong based on their personal view of Hussie as a person.
Am I supposed to see it as "everyone who likes Hussie is allowed to use he/him, but if they dislike Hussie then I have to be suspicious"?. Hussie makes it easiest to use he/him. Hussie calls herself an eboy on Instagram and has only ever broached the subject of gender to say "I don't care". I don't know if Hussie would disagree with either of you, but the position you put them in gives her infinite advantage over anyone who ever used he/him and doesn't like her. It's a convenient position for anyone as an individual, not a position one takes for the collective good, for the good fight or anything like that. It's transparently self-serving. The instructions were "any pronouns are fine". To change the intentions behind that so that anyone who dislikes you is stepping on a landmine for continuing to use the same he/him the people working with Hussie use is just... so wrong. I don't need to explain why that is, it's obvious to anyone that it turns it into a game played at someone else's expense.
Obviously you can jump down the throat of anyone who types Hussie's pronouns in italics, or bold or with quotation marks or whatever makes it obvious that they're making a point of expressing bigotry, but there has to be something to point at other than "you used the pronoun everyone says Hussie says is okay to use".
I'm not clowngender, because I reserve the right to care about my gender. I want to be able to talk about how the gender binary is harmful, and how the various positions I've been forced into or chosen to take in it throughout my life have been problematic for me, when I think that subject is worth discussing with somebody. I don't want any of my identity to be wrapped up in apathy, and I don't tell people to use any pronouns so I can catch them in a bind for using the wrong one. I tell them because I've reached a place where I feel comfortable with any and want to give them the freedom to choose the one they want. If I hadn't, if I had a favorite, I would be asking for the one I preferred like most people.
