Hmm. I think you could actually go a lot of interesting different places with a criticism of fen centering their reading on the orientation of the characters, but of course each place would get its own unique response. It's certainly intersecting the "Why slash?" question and the quality/kink dichotomy (which reared its head in interesting ways at WriterCon both in expected places--like kbusse's presentation--and unexpected places as the meta perspective and the how-to perspective interacted and sometimes clashed in fascinating ways; more on that when I discuss the science vs. magic panel, I think).
