Hmmm... being totally misinterpreted, I'm just gonna step out of the conversation...
Well, assuming you even read this, since you've left the conversation: Steve said the author's views don't matter because it's fiction. To me that sounded dismissive of fiction. Then you echoed it. If that is not what you meant (or if it's not what either of you meant it to sound like) why don't you both explain what was meant.
My contention is that it matters more because it's fiction. Because fiction can be more persuasive. People have some suspicion they might be lied to under other circumstances, but fiction can slip in right under their guard. Also, people don't always read critically, and especially not with fiction, where they can be in such a hurry to get on to the next thing that happens they rush on through without thinking at all. (It's not like in school where they expect to be tested and presumably pay more attention.) And many readers do believe that if a character said something—especially a character they like, and sometimes the characters they like are not very nice people—then that is what the author thinks, too. And it's not like that is never true. If we don't want other people to end up believing in something because we "said so" (something we would actually never think or say) then shouldn't we be careful of what we write and how we write it? If not to avoid causing offense, then to avoid being misinterpreted.
And it's not about conforming or being liked, Harpo. Right now, conforming and building up an adoring following among readers tends to require writing something harsh and bloody, with lots of violence against women, and lots of anti-hero characters. (Unless it is meant to be comedic.) Is that shifting? I don't think so, though it undoubtedly will eventually. Things do eventually change. But right now, in spite of all this talk about people being condemned for being offensive, the same authors (and their clones) are getting published and bought by readers this year as last year and the year before and the year before that and ....
