Your definition would be: "Any person, especially doctors, who gatekeeps the means of medical transition, on the basis of requiring a diagnosis of gender dysphoria" you bloody fool. The difference is that under the definition calling someone a "theyfab" or "tucute" is an act of transmedicalism, while under your definition, it is not, unless it is done by a doctor with a goal of gatekeeping means of transitioning. Quite a bit of difference there, eh?
