I loved this show. I remember watching it with my grandma one time, when she came out with, “Sherman Hemsley is gay, you know.”
“He is?!” I exclaimed. It was the first time anyone had ever told me an actor on a show I was watching was gay, anyway, but to have my grandma out Sherman Hemsley to me just blew my mind. “How do you know?!”
“I know,” she said matter-of-factly. “And he was much younger than Isabel Sanford.”
She was right about at least half of it: IMDb tells me he was more than twenty years younger than his Jeffersons TV wife.
