"The out butch lesbian that is big boned and wears a tux to prom and men’s clothes and the lipstick lesbian girlfriend wears dresses. I know several lesbian couples and none fit that stereotype. So the show is showing s stereotype."
First of all, I wouldn't describe that character as especially "big-boned" or "butch." But regardless, the fact that you don't happen to know any couples who fit that stereotype doesn't mean they don't exist. Are you suggesting that "lipstick" lesbians and "butch" lesbians can't be shown on stage (or screen, or whatever) because those characters then become "stereotypes?"
"I’d rather have the gay-guy version."
If the show did have two gay guys as the central couple, would you cry "stereotype" if one or both of them was somewhat effeminate or wanted to wear some traditionally female clothing or accessories to the prom?
