For chronological accuracy, I have been using the old name and gender when referring to a past, pre-transition person, and the new name and gender when referring to them generally.
But I had a realisation that this could be considered rude. I’d like to hear from some trans people on their opinion.
You are already doing great, you know ? You really seem to be a kind person and I get a better picture of your situation (thank you).
Yes, defaulting to post-transition name and gender certainly is the right thing to do.
Hope more people were interested as you are. Bye ^^
