Why not set it in alphabetical order? Like, "Bisexual, Gay, Lesbian, Transgendered" That would be more fair?
I find this rather offensive and sexist. It's like Yahoo is saying females are better, so therefore their group, lesbians, has to be first, and then comes bisexuals cause there are some girls in that group too, and at last comes the guys who are "gays".

babyronz: you are right, they would probably just rename this section "Lesbians - no gays allowed"
