Which isn't a bad thing in and of itself--I'm down with loving things, really--except when it begins functioning as a normative standard. But I remember just how often during the Diana Gabaldon affair and the discussions which followed, how often it was put forward that fanficcers were doing what we do out of love, as if that should matter somehow, and how problematic it was, this implication that it'd be right for us to be ashamed of what we do if we did it--when we do it--out of hate or anger or merely mild interest or simply because we can, that it's only because it's being done out of love that what we do is okay. And I really can't begin to describe just how damaging that seems to me, how pernicious I find the notion that really, fanfiction ought to be celebratory.
(Also how every year everyone angsts so much on whether their remixee for remixredux will like the remix they write despite being repeatedly told that's not really the point.)
It's helpful, I think, to have names--and names which don't begin with "Cult of," although they do I think they map fairly neatly onto what in years past have been called the Cult of Nice and the Cult of Mean--for these strands of media fandom, because they better help understand the diversity of opinion on some subjects such as the role of warnings, about concrit, or about the appropriateness of writing fanfiction with/out (asking) permission. The affirmational school focuses on privileging authors (including fan authors of fanfic) and their feelings; the transformational school, on open discussion and critique.
If there's any doubt about my own allegience, it's with the latter school, which has a wonderful history of producing such wonderfully rich, "thick" (in the litcrit sense) texts such as helenish's Take Off Clothes as Directed which subverts assumption about the use of BDSM as a fanfic trope, or these stories which do something similar with genderswap tropes, or the hilariously wonderful J2 fic Common Knowledge. (Recs for more fics with fall more on the transformative rather than affirmational side of fandom are totally welcome in the comments.)
These do not really seem to be, insofar as I can tell, particularly gendered phenomenon, no matter how much we might like to wave them off as being such. (It's interesting to look at how our instinctive gendering of the Cult of Mean/Cult of Nice divide and of the Affirmational/Transformative divide are actually completely opposite.)
This seems to me to be linked somehow also to this meme of "Fandom is my fandom": the notion that insofar as (what we have been calling) transformative fandom is affirmational, it's affirmational not of a text or an author but of a community readers who are also authors (and vice versa), a group of online contacts, and perhaps most of all a set of values which promotes dialogue and dicussion, critical response and critique, and, well, transformation.
