"Golden Opportunity" rejected by Interzone

But I got an interesting personally written rejection. The editor encouraged me to send another story in November, but basically outlined that neither editors at Interzone wanted to accept fairy-tale retellings, for the reason that they receive so many, and so many are crap, and so many are basically the same story with different trappings, that even if they accept the really, really good ones, they're just going to get a billion more sub-par ones in the mail.

Which I can understand.

The editor said to feel free to send another story which is not (their emphasis) a fairy-tale retelling in November.

The first day I got this, I ranted, "It wasn't a fairy-tale retelling! It's an exploration of a fairy-tale trope!" And then I came to my senses. It doesn't matter what I think the story is - it matters what the editor thinks it is. If the editor identified it as a retelling, than my arguing over specifics isn't going to change anything. I'm still going to send it out somewhere else, but the question remains: where?
