The medical profession is the core of the problem.

Yeah at some point they stopped giving medical advice and giving ideological advice. Also doctors who are not on board end up being brought in by HR departments or licensing boards. One of the things TRAs still complain about is that there are doctors who will tell them to find a gender specialist when they start trying to coerce the doctor into just signing off on whatever wild delusions they have that day. The doctor doesn't want to or perhaps can't legally push back.
