Amiyah Scott: 'RHOA' Treats Transgenders as a Joke ... I Quit!!!

Amiyah Scott was a wet dream for producers of "The Real Housewives of Atlanta," the prospect of a transgender cast member made them salivate, and she's so disgusted she just quit.

Amiyah was on the show for a trial -- the first transgender woman ever on the 'Housewives' franchise. We're told producers were prodding Amiyah to sexualize herself ... wearing lingerie and acting like a vixen.

We're told she bristled at the notes because she wanted to become a role model for other transgendered people. And we're told she was doubly insulted because they tried making her the bitch of the cast, trashing the other housewives.

After a month of filming, she walked off the set, saying she was done.

It worked out for Amiyah ... Lee Daniels has just cast her on a new TV show.
