In a post-Slash world I would have expected that this phrase would have died out by now:
"Keeping in mind that this volume is targeted at women, the editor seeks
mainly hetero stories, but will consider bisexual or lesbian encounters
and polyamorous relationships."
If you don't want the gay male stories that is your call, but it has nothing to do with 'keeping in mind' the general female-ness of the readership IMHO.
