Can a PhD (Or a doctorate or an MD) choose to use a gendered title instead of Dr? For example, suppose an AFAB PhD comes out as a trans man. Is he allowed to use Mister to affirm his gender? Or is he stuck in the gender neutral Doctor zone forever? Does he have to get knighted by the British monarchy in order to get a masculine title?
Most PhD’s in university actually prefer to be called by their first name. As a graduate student, one of the most jarring culture shocks is to learn to call professors by their first names. At least that’s the case in the US, not sure about elsewhere
