Yes. I know writers who consciously work through issues with their own beliefs in writing, but I'm trained to think that my inner working are not that interesting, and that belief is somehow a dirty word. I mean, I don't believe that, but enough people tell me off for the beliefs of my culture that I feel obliged to let them have control. Which irritated me, but I still feel I have to do it.
Hmm, clearly I should go to the SoA thing on responsibility to readers. Except it clashes with World Fantasy...
