Are gaydars really accurate?

Gaydar really exists, and is accurate, only for gay men in the detection and hooking up with other gay men. It works better for masculine men than for effeminate men, and it doesn't work for, or for the detection of, other genders or ual orientations. Like "the Force" in Star Wars, the more it is used and relied upon, the stronger and more accurate it becomes. And as with most peculiarly male and specifically masculine traits it is bitterly envied and vainly emulated by women and "trans folk," who, in frustration and despite, are wont to claim that it doesn't exist, since, obviously, for them it doesn't exist.
