Competently treating trans patients is more than knowing what medications someone is on. I know trans people that have had doctors strongly push medical detransition for having minor temporary health problems completely unrelated to their HRT. Immediately hitting the ‘medically detransition’ button every time one value goes out of range on one blood test isn’t competent care. Google ‘trans broken arm syndrome’. This stuff all has an effect on whether or not trans people seek care and how competent the care they receive is. If you set up in the minds of medical professionals that trans people are ‘actually’ their birth sex then you’re setting trans people up for receiving bad care, period.
