You keep acting like appearance essentially means nothing, which isn't true.Native Americans are not deemed 'Asian' on any official documents, as a practice. Descent is not race, and race is not a formal category in biology.
....which isn't how you use them. You said people use them how you use them. So that's not based on sex or gender, but purely on appearance, even if that contradicts sex and gender.
And if they've changed their sex?
Regardless of how you try to avoid admitting it, insisting pronouns of your choice apply to people that aren't you is enforcing your notions of identity on them.
You can't change your sex completely. And insisting pronouns are based on someone's own gender identity is forcing your definition of pronouns onto others. Do you not understand how this goes both ways? You're trying to have your cake and eat it too.
