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?
To be fair, lawyers get the much cooler Esquire, AND it is appended to the end of their name instead of the front. Definitely stands out more than the generic Doctor.
Although only a douchenozzle would insist on it being used.
