I would second all of this, except for the suggestion to delete it. It’s a common question.
To reiterate, “biologically male” means very little scientifically. Sex in biology is far more complicated than most people understand.
It doesn’t matter, because when we discuss gender socially, we’re not describing reproductive capabilities. We don’t stop calling women women when they go through menopause, for instance.
If someone wants to debate it, say no thanks. It’s a waste of your time. If someone asks in good faith, you can explain it if you feel capable, or shrug and say you’re not really sure, but it doesn’t matter.

I’m generally supportive of diplomacy, but I suspect that these delegations are only finding common ground on the worst fucking things.
