That's surprising given your continued use of male pronouns to refer to her.
I'm sorry if seeing news about trans people existing is an inconvenience to you, we just want to live without being ridiculed and sometimes killed. Visibility helps that because it shows people we are normal everyday people just like everybody else. If we hide and don't educate anyone, then we will still be treated like a strange and odd thing which is very bad for us.
That's not a matter of respect it's a matter of not being used to it, the entire things a process and I doubt that people will ever be able to completely switch the way they've always referred to something/someone on a dime.
Never in my life have I ever held ill will towards any group of people, maybe it's because surprisingly my Great Grandmother was never transphobic or homophobic or racist so I was always like "it is what it is and doesn't effect me" but I like many other people sometimes slip up when I try to refer to the gender of a transgender individual which i've done a few times with Caitlyn and it's not a matter of ill will it's a matter of adjustment.
Now I'm not trying to tell you to go easy on transphobic people because I never have when in discussions with them but if someones earnestly trying to get it right I'd try to give them some leeway which is what I tend to do when talking to non black individuals on race related issues.
Though i'm positive that the climate is much much worse in many ways for transgender individuals like yourself so if I was in your position there's no telling how i'd react.
Not that you're reacting badly at all.
