I forgot to respond to this the first time! That takes so much courage to be able to tell your family about something like that, even if they
are accepting of it. I'm a cis guy so I can't really know how that would feel, but it must be so offensive on such a personal level to not be accepted for who you really are. I think that people tend not to realize that gender is based on your brain, and it's not something you can be told, but something you, and only you, know with certainty. I think transphobia stems from a fear of anything that doesn't fit the convenient binary structure of how gender is perceived in society, and because your gender doesn't match your body that can freak some people out. But you can be stronger than them, because no one knows you as well as you do, and that's what makes you so valid and beautiful for standing up and telling them who you really are. With any luck, things will change, but sadly transphobia is such a deeply rooted issue that you might have to put up with that for a while... Regardless, I'm really proud of you for feeling comfortable enough here to come out, and it must have taken even more courage to tell your family. You have more courage for this than they will ever need to have.
(I hope that all made sense, but again, since I'm cis, I can't truly understand, so please correct me if I said anything inaccurate.)
I urge you guys to be open about your gender and pronouns
True! Although I doubt my thoughts on my own gender identity and expression would be very useful (because I'm pretty boring that way), I'm sure other people could benefit from this!
