Well, bonkers as it may be, still, there have been a couple of terrifying cases in America where medical professionals neglected to consider that their patient might be a transman - in one case, the transman (who didn't realise they were pregnant) had a stillbirth when earlier intervention might have led to a live birth; in the other case a transman neglected to mention this fact in the course of being treated for advanced kidney disease - and unfortunately blood levels which in a man indicate "keep an eye on this case, may need to progress to dialysis" indicate "about to die, look for a transplant right now" in a woman, which, biologically speaking, is what the transman was.
It is bonkers, but it's led to some dangerous cases, so I don't blame HCPs for covering their arse.
Nor is my beef with transmen who want to be referred to as "birthing individuals" or "chest-feeders" themselves. As just pointed out, it may not be the most psychologically healthy place for them to be, to live with that level of cognitive dissonance, but "not my circus, not my monkeys."
My only complaint is when that nonsense language is extended to me, against my directly expressed wishes.
