A long post, but one that rewards reading. Thank you.
I agree with you, as you phrase it carefully: “Can be impossible.” Not “Is,” but “Can be.”
Because…some authors are able to prevent their personal beliefs from leaking through into their work – but others aren’t. MZB let her feelings for child-adult sex leak through the boundary between author and work. But, in contrast, Orson Scott Card is pretty good at keeping his beliefs (against gays) from showing in his books.
So, for me, that isn’t the specific test… Because Card would pass it. I’m afraid I have to take a broader personal viewpoint, and boycott Card, because what he has said, entirely outside of the context of his books, was so outrageously and deliberately offensive that the odium contaminates everything he does.
(It’s a little like Rush Limbaugh doing ads for Snapple. I’ve never drunk Snapple since he did those ads. The product is permanently tainted in my mind.)
But here is the only real point I think I have: I acknowledge that this is at least partly irrational. I, myself, am smearing ideas across boundaries where they (perhaps) shouldn’t go. I’m practicing a kind of mental “magic of contagion.”
I’m one of those people who would not wear Hitler’s sweater. It’s not rational, but to me, the sweater would be “yucky” because Hitler used to wear it.
