I'm not talking about the gay dating site—I'm talking about the ability to 'sense' and identify whether a person is gay or not i.e. gay + radar.
Have you ever wonder why most gay people have gaydar whereas we've never heard of straight people having 'straightdar' i.e. ability to identify whether a person is straight?
I have a theory. Gay people have long been treated as something not in the norm of the society, e.g. by default, people would assume anyone is straight. The normal has always been for the straight but not for the gay. And when the society deems the norm to be straight, gay people have to find ways to look for people like them. That in turn makes them to gain the ability to observe very subtle clues. I believe if the perception towards gay and straight in the society was the other way round, the straight people would be the ones who gain their 'straightdar' and gaydar probably wouldn't exist.
I think gaydar is basically an ability developed in gay people (based on stereotypes on gay people themselves, i.e. what you think a gay person would behave like) due to human's social instinct to find a community they belong to. When not being used for finding like-minded people, I think gaydar is just really sharp observation skills.
IMHO there's some connexion between gaydar and gay people's fashion sense. Gay as we know are generally better than straight people in fashion sense and many are some of the best fashion designers. I don't think it comes by coincidence, nor it comes naturally. I would believe that by gaining gaydar, gay designers also gain sharp observation skills which in turn give them great fashion sense.
But I heard for some people, gaydar deteriorates over time. I've heard people used to be good in it lost it almost totally without apparent reasons. While I don't think one would lose its observation skills without apparent reasons, I can't find an explanation of losing gaydar.
But then again, not every gay person has gaydar. Some have never had it but probably still live a good life as a gay person.
So do you have gaydar? Anyone has already lost it? Have you ever put your gaydar in used other than finding gay people?
