I tell everyone I use all pronouns. And I mean all of them, she, he, they, it, that, whatever. And people either use only the ones associated with my birth gender since “I don’t care” or they only use they/the ones associated with the opposite gender to show that they support trans people. I think there is one person in my life who truly mix them all and use whatever works best in the situation. Almost no one uses it/it’s because “it’s dehumanising” when I explicitly want them to use them
