I've always just taken the route of (gently) reminding people when it comes to pronouns. Usually people will just take the hint after a few times. It sounds like you're pretty angry at the people who mess it up--which is understandable! It makes me mad too when people screw that up. >.< But, keep in mind that they probably aren't
intentionally doing this to hurt you. It's tough, but people, especially those who have known you for a long time, are probably going to keep making occasional mistakes by accident, no matter how accepting they are.
Of course, if you do repeatedly ask someone to call you she, and they persist in doing the wrong thing? >:I Well, that is super irritating, and I've been there. It might help to talk to the person one-on-one and try and explain how important it is to you.
In the end though, whatever! It's not about what people think about you, it's about you feeling good about yourself. So you can't let them get to you. Haters gonna hate.
