Spot on.
And best of all, being respectful doesn't require any effort! Just listen and be kind. Why heap misery on someone? If you think that's over-sensitive really you are the one lacking all empathy and kindness.
As a person who has a good friend who did the female -> male transition I will say that 'no effort' is not quite true. Despite my best efforts to respect his new gender, and supporting him 100% in his decision, I have a ton of history remembering him as female, and under a totally different name. That isn't easy to rewrite in your brain. Hell my mother occasionally refers to me with the dogs name. How brains link together the things we love and the way we feel is busted.
I make mistakes sometimes, I misuse pronouns sometimes. It's not an intentional thing, I'm trying as hard as I can to align my brain to his new identity... but it is hard. It takes practice, it takes effort, because if our brains have understood something a certain way for 10+ years, changing that is very difficult.
So I'm totally behind someone being whatever gender they want to be, but I hope you understand when I get things wrong. I'll support your change, if you can support my effort. Please don't doubt that it DOES take effort.
on a separate but similar note, if someone says "hey, I don't mind if you want to be whatever gender you present to me, I will treat you like said gender, if you want, but I think of things in terms of sex first" I have trouble saying they're an
awful person. uneducated maybe, insensitive maybe, but awful is a touch too far. I don't think this is quite the same as race because there's a difference between casual identification and the burden of knowledge on someone. If I met my transgender friend tomarrow for the first time, and said "whose the girl?" I can't imagine I can be properly called an asshole since I didn't know that he wanted to be male.
If someone said to me "I used to be male, now I'm female, if you don't add me to your potential date list, you're an awful bigot because you don't consider me completely female" I'm not sure that's just. There's a limit to what you can tell people to do to accommodate your feelings.
I dunno, I might be wrong, but I do think sometimes this outrage goes a little far. It's new territory for everyone, I think some understanding could be offered across both lines while people try to get their heads around things. I suspect more flies are caught with honey then vinegar.
