I remember seeing Liberace when I was growing up and there was nary a word from the adults about his nature. He was usually described as ‘flamboyant’ or ‘artistic’, which I suppose at the time were code words for homosexual. Even in the absence of any societal reference, I knew the guy was a Nancy boy and I knew he made me uncomfortable. I was slightly amazed he could behave that way in public and more amazed at the apparent density of the people around me that they couldn’t read this guy. It wasn’t till later I realized homosexuality had (and has) no place in civilized conversation.
I grew up watching non-gay heavy metal bands dressing up like women, wearing makup, and getting lots of hot young girls to fall in love with them. Maybe this is what destroyed my gaydar because I have absolutely zero gaydar.
Then again, that was a time when men did not discuss such things with children.
There is gaydar. Homosexuals like to deride that people can reliably tell who is gay, because they don't want to be outed by others.
Don't forget "confirmed bachelor".
Haven't heard that one in a long time.
Now John Travolta was a surprise I must admit.
