on the one hand, gaydar doesn't really exist and is more about social cues and heavily steeped in a bunch of assumptions about what the vibes of the gay people in your local community are

on the other hand, gaydar is a simple test that boils down to asking them "did you like the matrix 4"

@violet much less common but even clearer, asking about the Discworld adaptation The Watch. they made it very queer, it was a great series, lots of people were mad so it got terrible ratings lol
