I'm a jerk lol.
Of course, i say this, but i'm also fiercely non confrontational (My sister and I are both this way, it's our parent's fault. We grew up in a really volatile household so we both hide from arguments as adults)
Oh! My husband's sister does that to him ALL THE TIME. She calls him by a childish pet name he hasn't gone by since he was like 10 and he's asked her to stop and she never does.
I keep telling him he should refer to her by her full name out of spite because she doens't like being called by her full name and prefers the shortened form. I don't like my sister in law, she's a jerk.
I'm non confrontational sure, but I excel in passive agression hahaha.
I'm hopeful my sister will take it okay and that she'll try really hard not to misgender me. She actually knows how that feels because she has a gender ambiguous name that's more commonly used for boys in our home country. So growing up she used to constantly get mail addressed to "mr" and it used to really tick her off (I remember finding it amusing and not understanding why it upset her because I was like "Man, I want post addressed to mr!" oh hoh oho, if only I had understood hahaha)
She also has been called "mr" when people just see her name written down and haven't met her yet and make an assumption.
Suffice to say, my poor sister has been misgendered based on her NAME most of her life so i'm really really hoping that means she'll be better about adapting.
I mean, ultimately she has first hand experience right?
I do though hope I get the balls to call people the wrong gender if they aggressively misgender me hahaha, out of spite.
I mean I already do it online but online there's more like.. bravery because you're behind a screen.
