There’s always been gaydar. I think the straight folks who either can’t learn it (Christian Extremism and voting Republican are in that same locus) or won’t learn it (irony-impairment travels on the same gene) treat gaydar with the same kind of paranoia that makes people go to Epcot instead of going to the real countries.
It used to be that you could get around this ghastly lack by singing “Clang! Clang! Clang!” to a potential Matachine and if they respond with “Went the Trolley”, well, you have a bonafide (hehe, I said ‘bone’) homosexual on your hands (so to speak). But that’s an old song that most people probably don’t even know anymore.
There is a new hope, however: The KitchenAid Stand Mixer.
Got one? Then you’re a Big Ol’ ‘Mo. Sorry, you just are.
