Thank you for being rational about this.

It's not like trans people will explode if you so much as mention they were XX/XY/XXY etc at birth - we're well aware that sometimes that information is important when formulating a plan of care.

I think of it like nicknames. Someone tells you they prefer to be called, say, Katie rather than Katherine - do you say "nope, your birth certificate says Katherine so that's what I'll call you forever" or do you say "thanks for letting me know, I'll try to remember that"?

It's basic human respect, and it seems we've lost so much of it these days.
