Anyone who couldn't tell Liberace was gay back in the 60s needed a major adjustment to their gaydar.
But, but, but....gays weren't invented yet, were they?
I mean, it was well into the 1980s when Mother-In-Law asked me, "what is a homosectional?". And about the same time my own Mother asked me, "What is it those queer people do, anyway?" Both gray haired Grandmas were deadly serious.
