This is something that one needs to think about, and my rule is simply this: would you feel pleased and proud to have your work appear there?
There are some markets that sometimes people might want to exclude. Let’s take a (very) recent example, the Weird Tales kerfuffle. To recap, Marvin Kaye announced that the magazine would be serializing a novel, SAVE THE PEARLS, and his announcement made it seem as though part of the reason for printing it was that the book has been unfairly ganged up on by “Amazon readers.” I put that phrase in quotation marks because it’s actually been pretty consistently slammed for its racism by numerous bloggers. Here’s one of the reactions that sums up a lot of the objections.
The Internet, as is its way, spoke its mind on the subject. But beyond the slew of comments, there’s evidence that people are doing more than commenting. The withdrawal rate for the magazine as listed on Duotrope, is currently 25.86%, as in a quarter of the submitters have subsequently withdrawn their submissions. Compare that with Lightspeed’s withdrawal rate of 0.13% or Clarkesworld’s rate of 0.29% and you see that something’s going on.
Since then, the publisher has announced that they will not be serializing the book. That’s awesome, although it seems as though that announcement may be not entirely accurate.
But I view not sending something to a magazine because you object to its policies as not quite so important as this: don’t send to a magazine if you would not be proud to appear there. It’s about you, not the magazine.
Other markets that often come up in discussion include anything associated with Orson Scott Card or the Writers of the Future contest. Again, you need to think about it, not go with a kneejerk reaction. I have friends who submit to either or both of those, and that’s swell. They’ve thought about it, and reached a different conclusion than I might have.
As a feminist, I might have the same struggle with submitting to Playboy or Hustler (if they were taking unsolicited fiction, which they’re not.) As a writer, it’s your choice. Are you making a statement the magazine will listen to? Probably not. They’ve got literally hundreds of submissions coming in each month. You’re not going to affect them. The only thing you need to worry about is your own conscience and whatever decision you make is the right one if it works for you.
But also remember – the editor is not the magazine. I’ve submitted to a market I found problematic because I respected and liked the editor there. I entered WotF when I was still eligible because it was a heck of a sale and seemed like a decent career boost (alas, I never won, so I can’t tell you whether or not it was). My list of markets I won’t submit to is fairly small, and it’s been known to change. But I research and then listen to what my heart tells me. That’s what you need to do.
