And use "Marginal" instead of gay or queer or homo. "Fringe would be also okay, as in "On the fringe of the Bell Curve".
Normal is the perfect term.
I lived in San Francisco for years back when it was a safe city. There were many gay guys and lesbians, some very intelligent with good jobs, so I knew many. In my experience, the gay men were more mainstream than the lesbians, most were haters who thought men were horrible. Anyway, there were so. many of both gays and lesbians, they were’t exactly on the fringe there.
My dearest friend, the most beautiful woman imaginable, had a lesbian daughter was not good looking. . Of course she loved her anyway. I liked the daughter and so did my husband. I read last year that the daughter became a Trannie when she was 30. OK with me because she was over 30 when she did that and has a website that won’t let you read it unless you’re a member of the trannie group. So, she’s not a member of the Normal group but she’s a responsible citizen.
