As an otherkin; I can personally attest that I don't personally mind being called human; but that's because one of my OtherSelf entities is an angel; which is humanoid enough to confuse some.
So we don't consider it malicious usually unless it's done in a specific situation/context.
Fwy am also plural too; but we speak in unity as a System via Melody; our resident Flygon/Angel.
I don't mind speaking as if we are human though personally though; and do understand that some Others do not feel the same; as my partner in this realm most certainly dislikes some human terms. Fwy still gets occasionally corrected when fwy absentmindedly drops human words in conversations. It's something we're familiar with; and I'm genuinely glad the admin team is willing to hear things out and make things a little more inclusive where it makes sense when they can.
Fwy uses her own set of neos sometimes; in context when it makes sense among friendly folks.
So Fwy/fwyfwy/fwyself are all words you may occasionally see fwy use. Fwy doesn't make others use it though, we do appreciate it being used though; if someone addressing us can pickup the subtleties of it well enough to make the attempt. (Fwy promises it's not complicated)
Fwyself personally does use normal pronouns as well; such as She or singular They too; it helps confuse people less. Fwy sees no reason to throw up a barrier; only provide people subtle ways to signal intent or speaking context through either normal pronoun usage or fwyfwy neopronon usages; as that helps Fwy quickly route and allow the right entity to respond more quickly if they are used.
No one else in our System has ventured to publicise any neos yet besides fwyself; they simply don't seem to mind not having done so; particularly since using neos can get one singled out for harrassment fast in some internet communities.
