“centred around” is a subjective projection rather than statement of a fact in cases where gamete production genuinely does not occur. For this person, her gonads never developed into either testes or ovaries, so by this definition she would be of neither sex. I’m OK with that, but it does undermine your point about the strict binary.
My question to you is why does this matter, in the context of accessing bathrooms and changing rooms? Do you think inspecting reproductive anatomy is a proportionate measure?
More broadly speaking, what is the point of recording the ‘biological sex’ of a person who, through transition, has changed their physiology and endocrine profile to that associated with the opposite, and no longer has their natal reproductive anatomy? Who would this benefit?




He is being childish, but if I am completely honest, it sounds like you are a little too. Not in how bothered you are by the situation (understandable), but more how you perceive it.
I totally understand wanting to just do the work and cut the meaningless chatter, but the reality is a job usually has more abstract requirements outside of specific job tasks. One of these is getting your manager to like you. Social cohesion is one of the things workplaces tend to look for.
Not every manager cares about small talk perhaps as much as yours does, but that’s the situation you are in.
My advice would be to decide on one of the following 1) work elsewhere where you can thrive without this obstacle, 2) develop the skill of faking being interested, or 3) do nothing but get frustrated and possibly miss out on promotions or similar.
Wishing you the best, from a socially inept person with autism who relates to that dread, haha.
