A little bit of tact would have been nice also. Most people in our society are still not used to referring to trans people. I highly doubt anyone here is misgendering on purpose - even people who are aware of the underlying issues will still slip up sometimes, because use of gendered pronouns is reflexive.
Hell, I have a trans friend where I still struggle with correct pronoun usage. I've known her for a long time, and it takes a lot of conscious effort to override the reflex sometimes. We try, we're not perfect, so stop browbeating us about it.
