I heard back from another of the various publishers I've pitched, and to no one's surprise, they turned me down. In this case, they cited the fact that they already had enough anthologies lined up, and couldn't take on another. Fine, acceptable, everyone has their own projects to worry about. The next sentence, however, floored me and made me stop and blink.
"Although it pains me to say so, I think you'll do better with this one with an lgbt audience than an sf one."
I'm not going to tell you guys what I read from that statement. Let's just say my eyebrow hit the roof, and that I sincerely disagree. My belief is that an anthology of fantasy stories featuring themes of gender, sexuality, transformation, self-discovery, acceptance and exploration is still fantasy.
