That is really weird. I think I escape that myself because I basically do not write sex (not from any moral objections; it's just about as far from my forte as humanly imaginable) and thus the elements in my stories where I disagree with Lewis do not stand out as dramatically. Hmm. Now I kind of want to write a bunch of Narnians in an extramarital polyamorous sexual relationship, just for shock value. *sigh*

And yeah, like lady_songsmith said, you probably hit more problems than people like, oh, bedlamsbard would, if she posted on ff.net, because your stories do trend a lot closer to book canon and so the parts where you don't conform to a rigid, straitlaced view of Saint Lewis's Incomparably Pure Intentions (TM) come as an unwelcome surprise instead of as a confirmation of a prior bad opinion. The latter tends to make a person feel more secure in her/his worldview, but the former is an unpleasant jolt and may lead to lashing out.

Alas, speculation about potential motives is cold comfort to the person on the receiving end of said lashing out. Words DO hurt, after all. *deeper sigh*
