I have to wonder if granting any concessions to trans people is an act of kindness or a gateway to this kind of insanity.

Male and female are biological terms, and not up for magical reinterpretation, no matter how offended one gets.

Words are so critical to this, don't be bullied into making them meaningless.

If this person had said "now identifies as a (trans) woman" - is it reasonable to play along or is it inviting disaster? I truly don't know how to navigate this stuff.
