My mom and bro misgender me on purpose because me being female is the "truth". They constantly call me my birthname on purpose knowing that it frustrates me. The first person to get my pronouns and name correct irl was one of my friends mom. She's legit the only one besides my internet pals to not misgender me
Edit: I’m so sorry your family does that, that’s not at all okay and if you haven’t already you need to sit one or both of them down and express how awful they are being to you. If you feel that is unsafe for you, just try to be assertive at the time they do it but lay low as best as you can.
No one should do that, and I’m sorry you experience this regularly.
